Functional specialization (brain) In neuroscience, functional specialization is a theory which suggests that different areas in the brain are specialized for different functions.
What is functional specialization in psychology?
In neuroscience, functional specialization is a theory which suggests that different areas in the brain are specialized for different functions.
What is specialization of function among regions of the brain?
This article is about specialization of function among regions of the brain generally. For the particular topic of left-right brain specialization, see Lateralization of brain function. Functional specialization suggests that different areas in the brain are specialized for different functions. [1] [2]
What is the functional specialization of the left and right hemisphere?
The functional specialization of these hemispheres are offering insight on different forms of cognitive behaviour therapy methods, one focusing on verbal cognition (the main function of the left hemisphere) and the other emphasizing imagery or spatial cognition (the main function of the right hemisphere). [12]
Is there functional specialization in the human visual cortex?
A direct demonstration of functional specialization in human visual cortex. United Kingdom, London. Journal of Neuroscience, Vol 11, 641–649 ^ Pearlman AL, Birch J, Meadows JC (1979) Cerebral color blindness: an acquired defect in hue discrimination. Ann Neurol 5:253–261.
What is functional specialization in the brain?
In neuroscience, functional specialization is a theory which suggests that different areas in the brain are specialized for different functions.
What is meant by a functional specialization of the brain quizlet?
In terms of brain function, what is functional specialization? Each function or capability of the nervous system is controlled by a specific cluster of neurons in a specific area of the brain.
Why do you think that the brain has specialized regions for different functions?
Different parts of the brain function differently so that each area can do its job more effectively. The cells, or the cell networks, in any given area are specialized to perform a particular function as well as possible.
Is the specialization of functions in each hemisphere of the brain?
There is evidence of specialization of function—referred to as lateralization—in each hemisphere, mainly regarding differences in language functions. The left hemisphere controls the right half of the body, and the right hemisphere controls the left half of the body.
Which part of the brain is responsible for thinking and planning?
The frontal lobe, located behind the forehead, does much of the work of complex thinking, like planning, imagining, making decisions, and reasoning.
Which part of the brain is responsible for communication between the two hemispheres?
The corpus callosumThe corpus callosum connects the two halves of the brain and delivers messages from one half of the brain to the other.
Are brain functions localized?
Normal functioning: Primary sensory and motor functions are localized but higher cognitive functions are distributed within large-scale networks.
What does functional localization mean?
refers to the idea that functions can be attributed to specific regions of the brain.
What is functional connectivity in psychology?
Functional connectivity is defined as the strength to which activity between a pair of brain regions covaries or correlates over time.
What do you mean by specialization?
Definition of specialization 1 : a making or becoming specialized. 2a : structural adaptation of a body part to a particular function or of an organism for life in a particular environment. b : a body part or an organism adapted by specialization.
What is right left brain hemisphere specialization to?
Handedness and brain asymmetry are widely regarded as unique to humans, and associated with complementary functions such as a left-brain specialization for language and logic and a right-brain specialization for creativity and intuition.
What is hemispheric specialization quizlet?
Hemispheric Specialization / Lateralization of Function. -Differences in processing between the left and right hemispheres of the brain.
Which part of the brain processes incoming information to coordinate and regulate movement?
The Hindbrain It consists of the cerebellum, pons, and medulla. The cerebellum — also called the "little brain" because it looks like a small version of the cerebrum — is responsible for balance, movement, and coordination. The pons and the medulla, along with the midbrain, are often called the brainstem.
Is the cerebral cortex the largest part of the brain?
The cerebrum is the largest part of the brain whereas cerebral cortex is the outer layer of the cerebrum. The cerebral cortex is made up of gray matter (comprises cell bodies and dendrites) that covers the internal white matter.
What behavior is most directly tied to the cerebellum?
Coordinating movement: Most body movements require the coordination of multiple muscle groups. The cerebellum times muscle actions so that the body can move smoothly. Vision: The cerebellum coordinates eye movements. Motor learning: The cerebellum helps the body to learn movements that require practice and fine-tuning.
Which lobe of the brain contains centers for auditory and language input?
The function of the temporal lobe centers around auditory stimuli, memory, and emotion. The temporal lobe contains the primary auditory complex. This is the first area responsible for interpreting information in the form of sounds from the ears.
Historical origins

Major theories of the brain
Currently, there are two major theories of the brain's cognitive function. The first is the theory of modularity. Stemming from phrenology, this theory supports functional specialization, suggesting the brain has different modules that are domain specific in function.
How do scientists explain the brain?
Today, the practice of the day is all about computers and computation, and so many scientists are trying to explain the human brain by saying that it works like a computer. In the next century, once society moves beyond computers, future generations will laugh at this and think that it was stupid to think that the brain works like a computer!
Who was the first scientist to explain how the brain works?
An Austrian scientist called Franz Joseph Gall promoted the idea that there are specific centers in the brain for specific functions [ 3 ].
How do we learn about the brain?
We do this by implanting electrodes inside the brain (see Figure 1 ). These electrodes work like “spying microphones” implanted in different regions of the forest. We listen to the electrical activity and we try to decipher the code of such activity. To do this, we remove the skull bone and gain direct access to the surface of the brain.
How does 50 Hz affect the brain?
We perturb the function of a brain area by sending 50 Hz electrical pulses through the pair of electrodes that are touching the brain. If you remember, the brain cells work with electricity. If you send additional electrical pulses at a random frequency of 50 Hz, you make them confused.
What is the idea that if you use a part of your brain frequently, you become very good at it?
This idea, known as phrenology, argued that if you use a part of your brain frequently, you become very good at it, and that particular brain area grows in size and creates a little bump in the skull bone. Let's say we have a math center in the brain. If you use math all the time, you become very good at it.
Why are brain cells connected?
Because brain cells are connected together, brain functions are then created in a collective action of connected areas. It is like a city with different neighborhoods, and each neighborhood depends more or less on the other neighborhoods.
How do brain cells communicate?
Another fascinating thing about the brain is that its cells produce electricity, and that brain cells talk to each other by sending electrical signals. Now imagine that you are sitting in a helicopter and looking down at a dense forest. You see a lot of branches touching each other, but you do not hear much. If you now send a microphone down, you can start hearing all sorts of things: birds are singing, leaves are falling, monkeys jumping around, and jaguars are walking. So if you implant these spying microphones for days you will learn a lot of interesting stuff about the forest life. This is what I do for living: I listen to the sounds of the brain and try to understand how the brain works by recording the electrical activity from different corners of the brain. Listen to this video if you are interested in “sounds” of the brain.
