What is the nervous system made up of?
The central nervous system (CNS)
The peripheral nervous system (PNS)
What 2 systems is the peripheral nervous system (PNS) made up of?
The somatic system
The autonomic system
What is the central nervous system (CNS) made up of?
Brain
Spinal cord
What are neurons?
Basic building blocks of the brain
What 3 things do neurons do?
Born
Migrate
Differentiate
What parts make up a neuron?
Cell body Dendrites Nucleus Axon Myelin sheath Axon terminals
What is Hebb’s rule (1949)?
Neurons in the brain that are simultaneously or successively active become associated.
What is resting potential?
The difference in electric charge between the inside and outside of a (neural) cell membrane.
What is action potential?
When a stimulus reaches a resting neuron, the neuron transmits the signal as an impulse. This is called action potential.
What is synaptic transmission?
The passage of an electrical impluse from one neuron to another via neurotransmitters.
Where is the occipital lobe located in the brain?
At the back
Where is Broca’s Area located in the brain?
At the front
What are the functions associated with the frontal lobe?
Problem-solving Social functioning Deployment of attention Goal-directed behaviour Self-regulation
Case study used to identify behaviours associated with frontal lobe
Phineas Gage
Case study: Phineas Gage
Railroad engineer who places detonate explosives along developing railroads
Accidentally placed the tampering iron on the explosive
An iron bar penetrated the right-hand side of his skull, passing through the left-hand side of his frontal lobe and exiting through the right frontal bone
No longer reliable/considerate
Experienced poor judgments and deficient social skills
