Brain structure + Neurotransmitters Flashcards
Brain structure, neurotransmitters, neurons and rec. drugs
Name the four lobes in the cerebral cortex.
Frontal, Parietal, Occipital, Temporal.
What is the frontal lobe responsible for?
High-level cognitive functions (thinking, planning, problem-solving, controlling behaviours and emotions).
What is the parietal lobe responsible for?
Senses (somatosensory cortex) from skin (contralaterally) and process location, volume and pitch.
What is the occipital lobe responsible for?
Inc. primary and secondary visual cortexes (respective field of vision in both eyes controlled by the opposite side).
What is the temporal lobe responsible for?
Understanding of language, facial recognition, hearing and speech.
The spinal cord in the CNS is responsible for…
Reflex actions, message transfer to/from brain, link to peripheral nervous system.
The brain in the CNS is responsible for….
Conscious awareness and decision-making.
The limbic system is made of two of each…
Hippocampus, amygdala and hypothalamus.
Hippocampus is responsible for…
Memory formation and spatial navigation.
Amygdala is responsible for…
Emotional response especially to fear/anger, ‘fight or flight’ reaction (self-preservation).
Hypothalamus is responsible for…
Automatic functions/regulations (temperature, hormones, hunger/thirst, sex) and controls amygdala’s fight/flight stress response.
The cerebellum is responsible for…
Coordination of muscle coordination, balance and movement (spinal cord/motor cortex)
The brain stem contains and is responsible for…
Relay of sensory information from CNS and medulla - unconscious activites
The corpus callosum…
Connects the hemispheres of the brain, integrating both sides’ activities together.
GABA (Gamma-aminobutyric acid)
Inhibitor (Can inhibit the inhibitor of other neurotransmitters, increasing overall levels)
