35
Medulla
- connects brain and spinal cord, pathway for neural signals - regulate autonomic processes, (respiration, heart rate, blood pressure, digestion) - controls reflexive actions (vomiting, coughing, sneezing) - subconscious and are fundamental to survival Damage = often fatal (e.g. blow to back of head)
36
Pons
- located above medulla (small bundle of nerve tissue) - regulates respiratory system & controls sleeping, dreaming, & waking. - involved in involuntary behaviours (blinking) - relays info between brain areas, (cerebral cortex-cerebellum) (medulla-midbrain) Damage = often fatal/develops locked-in-syndrome (no sensory/motor function, except moving eyes up and down, or blinking)
37

41
Thalamus
- filters info from sense receptor sites (except nose), passes to relevant brain areas for further processing. - relays motor signals b/w higher & lower brain areas involved in motor control (relaying sensory and motor signals) Damage = visual or hearing impairment or inability to feel sensations when touched
42
Cerebrum

43
Cerebral cortex
the outer layer of the cerebrum that covers the brain - composed of 3 functional areas: motor, sensory & association - divided into 4 regions: frontal, parietal, occipital, temporal (FPOT)
44
Functional areas
motor areas - initiating & executing motor movement, made of motor neurons sensory areas - receiving & processing sensory info, made of sensory neurons association areas - integrate info from motor & sensory areas to execute complex processes
45
Frontal lobe
- largest of the four lobes - located in the upper forward half of each cerebral hemisphere Association and motor areas: - prefrontal cortex - premotor cortex - primary motor cortex - broca's area
46
Prefrontal cortex, premotor cortex, primary motor cortex
Prefrontal cortex: behind the forehead - association area - reasoning & logic, planning, problem-solving, decision-making, attention, emotions, reactions, self-awareness, personality - plans required motor sequence & sends instruction to premotor cortex Premotor Cortex: - motor area - organises movement sequence - prepares movement sequence & sends to primary motor cortex Primary motor cortex: - motor area - controls voluntary movement through skeletal muscles - PMC in left lobe controls right side of body (vice versa) - sends signals to cerebellum to do movement Prefrontal --> premotor --> primary motor
47
Broca's Area
