PSP Unit 3: The Brain Vocabulary

Cerebrum

Area of the brain responsible for all voluntary activities of the body

Cerebellum

the "little brain" at the rear of the brainstem; functions include processing sensory input and coordinating movement output and balance

Brain Stem

Connection to spinal cord. Filters information flow between peripheral nervous system and the rest of the brain.

Hemispheres Of The Brain

The human brain is divided into two halves called the left and right hemispheres

Neurons

Individual cells in the nervous system that receive, integrate, and transmit information.

Axons

Conduct impulses away from the cell body

Neuroplasticity

The ability within the brain to constantly change both the structure and function of many cells in response to experience or trauma

Synapse

The junction between the axon tip of the sending neuron and the dendrite or cell body of the receiving neuron

Dendrite

The bushy, branching extensions of a neuron that receive messages and conduct impulses toward the cell body

Adrenaline

A hormone released into the bloodstream in response to physical or mental stress

Endorphin

Chemical in the brain that plays a specialized role in pain reduction

Serotonin

A neurotransmitter that affects hunger, sleep, arousal, and mood.

Dopamine

A neurotransmitter associated with movement, attention and learning and the brain's pleasure and reward system.

Malleable

Easy to shape or bend

Brain Plasticity

The "plastic" nature of the brain AKA it's malleability or it's ability to change.

Neurogenesis

A process for adults to possibly create new brain cells, which was at first thought to be impossible at first.

Neurons That Fire Together, Wire Together

The more you do something over and over and over again, the better the neural pathways inside of your brain will be linked, or wired together to make your learning better.

Neurons That Fire Apart, Wire Apart

The more you forget something, whether it's for weeks, or even months, the worst the neural pathways will start to break apart each other, and will not increase your learning.

Functional Plasticity

The brain's ability to move functions from an area that's damaged to an area that is undamaged.

Structural Plasticity

The brain's ability to actually change from a physical structure to a learning result.

Epigentics

First introduced by Researcher Bruce Lipton, this is an "entirely new branch of biological science". A person's DNA changes continuously based on one's experiences, emotions, and environment.
