Where are concept cells located?
Concept cells in the MTL are situated at the summit of the processing stream and receive information from higher-level areas about the perceptual state of the subject.
When conducting an experiment on how stimuli are represented by the firing of neurons?
When conducting an experiment on how stimuli are represented by the firing of neurons, you notice that neurons respond differently to different faces. For example, Arthur’s face causes three neurons to fire, with neuron 1 responding the most and neuron 3 responding the least.
How is a specific person’s face represented by the nervous system?
A specific person’s face is represented in the nervous system by the firing of: a group of neurons each responding to a number of different faces.
What is the study of the physiological basis of cognition is known as?
Cognitive neuroscience is the scientific field that is concerned with the study of the biological processes and aspects that underlie cognition, with a specific focus on the neural connections in the brain which are involved in mental processes.
Which part of a neuron transmits signals to other neurons?
A neuron has three main parts. The cell body directs all activities of the neuron. Dendrites extend out from the cell body and receive messages from other nerve cells. An axon is a long single fiber that transmits messages from the cell body to the dendrites of other neurons or to other body tissues, such as muscles.
Why is white matter white?
White matter, which lies beneath the gray matter cortex, is composed of millions of bundles of axons (nerve fibers) that connect neurons in different brain regions into functional circuits. The white color derives from the electrical insulation (myelin) that coats axons (see the figure).
What are nerve signals?
A nerve impulse is the way nerve cells (neurons) communicate with one another. Nerve impulses are mostly electrical signals along the dendrites to produce a nerve impulse or action potential. The ions are moved in and out of the cell by potassium channels, sodium channels and the sodium-potassium pump.
What 3 things make up the nervous system?
The nervous system consists of the brain, spinal cord, sensory organs, and all of the nerves that connect these organs with the rest of the body.
What are nerve cells called?
The basic unit of communication in the nervous system is the nerve cell (neuron). Each nerve cell consists of the cell body, which includes the nucleus, a major branching fiber (axon) and numerous smaller branching fibers (dendrites).
Is being nervous a good thing?
In the book, Cuddy outlines two key reasons why a moderate amount of nervousness can be helpful in stressful situations. For one, anxiety can be an adaptive response that keeps us alert to danger and things going wrong. Sometimes, Cuddy says, nervousness can also signal respect for the person you’re interacting with.
Is Peer-to-Peer illegal?
Sharing work or media through a peer-to-peer (P2P) network is legal if you own the copyright, thus you own the right to determine if and how that work is distributed. However, it is illegal for you to download or share copyrighted works without permission from the copyright owner. …
How do peers influence you?
These peers also influence you by the way they dress and act, things they’re involved in, and the attitudes they show. People are influenced by peers because they want to fit in, be like peers they admire, do what others are doing, or have what others have.
Who is considered a peer?
A peer is someone at your own level. If you are a 10th grader, other high school students are your peers. Peer comes from the Latin par which means equal. When you are on par with someone, you are their peer. If kids your age are pressuring you to do something you don’t want to do, that’s peer pressure.
Is peer pressure a good or bad thing?
Peer pressure is not always a bad thing. For example, positive peer pressure can be used to pressure bullies into acting better toward other kids. If enough kids get together, peers can pressure each other into doing what’s right!
What is peer in psychology?
a group of individuals who share one or more characteristics, such as age, social status, economic status, occupation, or education. Members of a peer group typically interact with each other on a level of equality and exert influence on each other’s attitudes, emotions, and behavior (see peer pressure).
