Exam 4: The Biological Basis of Mind and Behaviour

Axons that make up the white matter of the brain and spinal cord as surrounded by myelin, cells that accelerate the speed of neural communications.

Neuroscience is best defined as

This early pseudoscientific theory of brain function held that the physical anatomy of the skull could be analysed to reveal the workings of the human mind.

This outer layer of the cerebrum enables humans to interpret sensory information, solve problems, learn, remember, and use language.

Neurons are not fused to each other so neurotransmitters must pass across the

This structure, severed in so-called "split-brain" patients, allows neurons from separate cerebral hemispheres to communicate directly.

Also called the soma, this part of the cell contains the nucleus, where most of the genetic material for the cell is stored.

The principal cell for communication in the nervous system is the

_________neurons transmit information toward the spinal cord and brain, while _________neurons transmit information from the spinal cord and brain to the body.

The anatomy of the neuron includes four very important regions: dendrites, cell body, axon, and terminal. Define each region and explain how each region contributes to an action potential.

These projections reach out from the cell body of a neuron.

Seated at the base of the forebrain, this relaying structure is thought of as the "gateway" to the higher functions of the brain.
