The brain Flashcards
Lobes of the brain
Frontal, parietal, occipital, temporal
frontal lobe -> cortex
primary motor cortex
pariteal lobe -> cortex
somatosensory cortex
occipital lobe -> cortex
primary visual cortex
temporal lobe -> cortex
primary auditory cortex
what is the forebrain split into
hypothalamus, thalamus and cerebrum
what is in the midbrain
reticular formation
what is in the hindbrain
cerebellum, pons, brainstem and medulla
the hypothalamus is responsible for…
producing hormones to control basic survival actions (body temp, heart rate, hunger)
the thalamus is responsible for…
the relay station for sensory and motor information
the cerebrum is responsible for…
higher cognitive functions
the reticular formation is responsible for…
regulating arousal and consciousness
the pons is responsible for…
receiving visual stimuli
the cerebellum is responsible for…
coordinating body movement
the brainstem is responsible for…
vital functions of life (breathing, consciousness, blood pressure, heart rate and sleep)
the medulla is responsible for…
the regulation of vital involuntary bodily functions essential for survival
the cerebral cortex is responsible for…
higher cognitive functions, sensory perception and motor control (protective layer)
what does the primary motor cortex do
initiates voluntary movement
what does the primary somatosensory cortex do
detects sensory information from the body
what does the primary visual cortex do
processes visual data
what does the primary auditory cortex do
processes sounds and speech
contralateral organisation states that…
messages from left side of the body will be responsible for actions on right side of the body and vice versa
hemispheric specialisation is
the concept that one hemisphere has specialised or exerts greater control over particular functions
contralaterised vs laterised
contralaterise means they work together
laterised refers to a certain hemisphere of the brain is generally responsible for a certain area
