Cognitive Neuroscience of Attention
This cognitive neuroscience bitesize video explains how attention has limited capacity and is therefore linked to prioritization of competing information. This is achieved through enhanced brain activity that is sustained by frontal-parietal circuits. A comparison between neural representations in parietal and visual cortices is made.

Semantic Memory: Words and Concepts in the Brain
มุมมอง 3542 หลายเดือนก่อน
This cognitive neuroscience bitesize video explains how (and why) concepts are represented by a distributed network of regions in the brain and whether there are also central regions (or hubs) within that network that help to bind the features together.
The Frontal Lobes and Executive Control of Cognition
มุมมอง 6942 หลายเดือนก่อน
This cognitive neuroscience bitesize video explains how the prefrontal cortex coordinates the activity multiple brain system through biasing signals, and how different parts of the prefrontal cortex (e.g. orbital v. lateral) control different aspects of behavior.
EEG - Electrical 'Brainwaves'
มุมมอง 31K4 ปีที่แล้ว
This cognitive neuroscience bitesize video explains EEG in terms of how the brain generates electrical signals and how we can use these (as event-related potentials) to understand the neural basis of cognition.
NIBS - Non-Invasive Brain Stimulation in Cognitive Neuroscience
มุมมอง 11K4 ปีที่แล้ว
This video, part of the cognitive neuroscience bitesize series, gives a brief overview of brain stimulation methods and contrasts them with recording methods. The methods of TMS (Transcranial Magnetic Stimulation) and tES (Transcranial Electrical Stimulation), including tDCS and tACS, are discussed in terms of their effects on the brain and how this can be used to understand cognitive processes...
Vision for Action: The Dorsal Stream
มุมมอง 13K4 ปีที่แล้ว
Part of the cognitive neuroscience bitesize series, this video describes how visual information interfaces with action in the dorsal stream which runs from occipital to parietal regions. It considers the different effects of ventral and dorsal stream lesions on action and perception, and considers the different mechanisms within the dorsal stream that are linked to hand and eye movements, and r...
Object Recognition: The Ventral Stream
มุมมอง 10K4 ปีที่แล้ว
Part of the cognitive neuroscience bitesize series, this video describes the process of translating basic-level visual processes into meaningful object-level representations. This involves a consideration of Gestalt grouping and the principle of object constancy. The ventral stream is considered in terms of the response properties of neurons (and voxels in fMRI), and their response specificity ...
Networks in the brain: mapping the connectome
มุมมอง 20K4 ปีที่แล้ว
Part of the cognitive neuroscience bitesize series. This is a follow-up of 'basics of fMRI' that considers exciting developments in mapping the human connectome. It covers basics of structural connectomics (diffusion tensor imaging) and functional connectomics (resting state, and task-based correlations of the BOLD signals), and introduces concepts such as small-world networks.
Specialized visual processes: color, motion and shape
มุมมอง 2.1K4 ปีที่แล้ว
Part of the cognitive neuroscience bitesize series! This covers more specialized cortical visual regions involved in color (area V4), motion (area V5/MT) and shape (LOC, lateral occiptal complex). Draws on evidence including patient-based neuropsychology (e.g. achromatopsia, akinetopsia) and fMRI (explaining the principle of BOLD adaptation).
Early visual processes in the brain
มุมมอง 6K4 ปีที่แล้ว
Part of the cognitive neuroscience bitesize series. Aimed at undergraduate students. This covers different routes from the eye to the brain; the layout of primary visual cortex (including cortical blindness and blindsight); and the response properties of neurons in this region (the hierarchical view of vision from Hubel and Wiesel).
Basics of fMRI
มุมมอง 27K4 ปีที่แล้ว
A brief (under 15 mins) tutorial on the basics of fMRI for the cognitive neuroscience bitesize series. Covers the physics of MRI; structural and functional imaging; the haemodynamic response and how we can link it to cognitive processes. Aimed for university students in psychology and neuroscience.

You explain this so well
Thank you so much, you explain it so clear and it is great to watch this right before my exam to just quickly review some things!
I HAVE NO MENTAL PRIVACY OR PHYSICAL PRIVACY EVER DUE TO CRIMINALS READING MY EEG DATA ON A CONTINUAL BASIS. I am a targeted individual which means that I have been illegally implanted with injectable self-assembling implants which have now permeated my body and brain and this has occurred against my will and without my awareness or consent. I have nano electrodes and other nano technology inside my brain and body. Unknown criminals now both send and receive data to and from my body and brain from unknown remote locations while they remain unknown to me. I am sixty four years of age and I live alone in a rural location. I have been targeted by these unknown criminals for more than twenty one years. This evening which is dated the 18th November, 2024, at 5.15 pm G.M.T. I was alone inside my own privately owned home and I had the outer doors locked and security chained. I was in my shower room and I was sitting on the toilet. The EEG data which my brain generates is being continually transmitted to the criminals where that EEG data is then automatically translated into the thoughts I think, the feelings I feel, the muscles I move, the words I hear, the images I see and whether I am sitting down or standing up or moving about. The fact that I was sitting on the toilet in my own home was known by those criminals who illegally steal my EEG data because such information is always continually available to them. As the illegal system which connects me with those criminals is a two way system they both steal data from my body and brain and they transmit data to my body and brain in the form of voices, images, forced muscle movement, electric shocks, pain, cramps, and in a number of other unwanted experiences. While I was sitting on the toilet in my own home alone with the doors to my home locked a voice was heard by me to say the following:- "Why is she clutching her knickers". One of the men who remote neural monitor my private EEG data read from the EEG readout that I was sitting on the toilet and I was holding on to my knickers. He may have been brain to brain interfaced with me but I don't know the whole situation of what is happening behind the scenes among the cowardly and cruel remote neural monitoring and remote neural manipulating team. Earlier on this afteroon at 3.50 pm G.M.T I was using my computer and I was online. I then felt a painful sensation coming from my foot and I knew that one of the remote neural manipulating team had deliberately transmitted a pain signal to my foot. I grimaced in pain. Another member of the remote neural manipulating team was then heard by me to say the following to the remote neural manipulating team member who had transmitted the pain signal to me, the following:- "Do you have to do it in front of the screen." I believe that I can be observed through my computer screen at some level especially when I am online. That must be the reason that I am mostly allowed to be free from electronic harassment while I am online while using my computer. My name is Gretta Fahey and my postal address is Newbrook, Claremorris, Co. Mayo, Eircode F12 Y560, Republic of Ireland.
Excellent!!
Great video! Thank you!
First
Thanks for elaborate key insights on the human brain connectome project.😊❤
GET RID OF THIS DIABOLICAL INVENTION. GET RID OF IT. THEY'RE GONNA USE IT TO READ OUR MINDS. THIS IS THE DEVIL'S WORK AND EVIL PEOPLE'S WORK. LISTEN TO ME.
FYI, the audio has to be remastered to a constant volume.
This is amazing. Can we fix the audio please to make the sound clearer.
Interesting content, but the soubd quality of your video makes it difficult to understand what you are saying. A good mic will solve that iussue if you want to.
So, neurons may have a Bacon number?
😊jak przetłumaczyć film na język polski ?
where is the other half of the chapter ?
here
Could you please help me understand what is actually happening in that area when it is either, p+ or n- ?
Thank you so much for this video! You make it even more interesting for me
Hi.. i need help.. i need to know..can our brain react unconsciously by doing or imitating an action we have already done in a few seconds, especially in a state of surprise, for example we are driving on a right turn and suddenly there is a motorcycle in front and we unconsciously react to the right of the road as well to prevent accidents
Sounds like a lot of non committal verbiage , ie “might”, “could”. I wish there was some legitimacy to this concept
Thank you for explaining this in a way that actually makes sense.
Look at me I'm a God.. 🤡
I believe the illuminati has the ability to make people's minds weak and vulnerable which would stem from the mkultra interigation aspect for the cia mkultra projectand can use it to control people by making that feeling very real and terrifying to someone then ur brain doesn't know the difference
great video!! very helpful for my cognitive science course :)
Finally a comprehensive explanation
thank you so much :')
Is there a snake in your tree? Thank you for your content.
It worths thousand likes, thank you
...Thnxs for sharing...
great content but no music please. thanks from Brazil
If you think that's complicated, just consider his brain was able to completely render that entire thought of the concept of itself and relay it to us
Thank you so much for this video. I have a quick question. I know someone who was being treated for cognitive decline with non-invasive neuromodulation. During their session I was told that their head felt that their head was on fire. This was during the session in which it was the first session after their first 16 sessions so they were coming back from a break and was told that it needed to be revved up higher. After experiencing pain they started to experience headaches which have not gone away. Have you ever heard of neuromodulation causing headaches from over stimulus? Thank you so much for your insight and feedback I truly appreciate it.
my 2 cents , could have been causing actual heat, they should have actual , real thermometers around. There are known failures of medical devices that overdosed patients.
THANK YOU! ! ! Is an EEG dangerous to others who may view it being administered? If not why would the Dr./Nurse/Tech not want a family member to observe? PLEASE reply. Thank you. :-) Another question. Do EEG's detect different types of brain waves? Please reply.
I'm overly thankful for this video, thank you very much!
excellent presentation !!thank you !
A must-read, lucid and wide ranging, is Prof Nina Kraus' recent book 'Of Sound Mind'. As a musician/neuroscientist she has particular insight. A must-hear, on her Brainvolts website, is the recording via electrodes of what a subject is hearing. Not exactly hi-fi, but completely recognisable on music and speech! I have no connection with Prof Kraus, and am no academic, but have been busy in sound creation lifelong. It's great to go on being astonished! Apparently the ear is even more engaged with the mind, two way, than the eye.
Did you edited the video and sound with a potato?
Wonderful work Thanks Go on May Allah bless you
How are the editions different to one another?
SÓNG NÃO BRAIN WAVE 🧠🧠 ĐỘI MŨ ĐIỆN CỰCK LÀ KHÔNG CẦN THIẾT, SÓNG ĐI XA LẮM LẮM ĐÓ, CONTACTLESS .... NHÀ KHOA HỌCK TÂM THẦN DOCTORỒ PRỒFESSOR BQC BÙI QUANG CHÍNH.
The dorsal pathway of language generation is one of the most important concepts I have ever had the pleasure of wrestling with. In essence, when a motor plan of language is observed to be in the mind's awareness, the dorsal pathway has already been put into place and its motion begins to unfold with or without a conscious observer. If no conscious observer initiates the plan, then it unfolds in a very different manner than if a conscious observer is present. The radius of darkness, or prosody, expands as a radius in both hemispheres through a mirror image reflected spherically through the vertical plane dividing the hemispheres of the frontal lobes. As the light of the motor program emerges along the spherical surface, linear path along its outermost surface is followed by the muscles to expand and contract with the shape of the path created by the radius from the sphere's center, if the program is consciously initiated at the time it emerged. As the radius turns round, up or flat and clockwise, it generates an outward extension of sensory energy that can be seen by the tongue as the muscle pattern of movements required to produce speech... only if a conscious observer is present to control the actions. As the radius turns, a mirror image in the right hemisphere is produced and perceived, until the radius has traversed the 9 o'clock through 12 o'clock span, with the horizontal rotation consuming the light of sensory information coming out of the radius of curvature parallel with its flat plane beneath, with the vertical vector arising from the curvature of prosody injected into the pure sound pattern of light in order to shape the the intended meaning. The left hemisphere is guided by our own intuition and personality for when to initiate the processing of the light into motor actions, and when to pause the program and ascend vertically with time. Of course, most of the time we carefully balance the two, producing speech at appropriate rates,, with appropriate timing as best as we are able. The right hemisphere is used to fold the left and right mirror images above and below each other, compressing the initial expansion into an arc the fraction of 180 degrees, and creating the first image of meaning projecting from directly behind the central origin from which it emerged... directly to its front and center. It involves cerebellar, brainstem and many other things... Once the first segment is processed, the plane of motor program is tilted on the top of the prosodic curvature, and the next segment builds upon it according to its own intelligent design. This model is way different than my 6-6-6 experience, and no wonder it took me over 30 years of work to figure it out. Once it reaches a 90 degrees vertical arc, it spirals to a point, as the other side's mirror image also spirals to a point. If an observer is not present, then the generated language vectors follow a different path, and I will keep this to myself for now. I'm tired. Our conscious minds create space-time containments separated from gravity.
Phenomenal . Thankyou so much
Thank you very much, I feel much more confident going into my neurobiology midterm! CHEERS
Not going to watch this but they experiment on unknowing and unconsenting people
I love to have this done I'm stroke survivor 🧐
very informative, cheers
