Regions of the Brain

Forebrain - frontal lobe - Language production

• Halting speech • Disordered and repeated words • Good comprehension

Forebrain - parietal lobe - Speech comprehension

• Fluent speech • Minimal repetition + adequate grammar • Bad comprehension

1) Hindbrain 2) Midbrain 3) Forebrain

Hindbrain - Cue: “without it, me die” - Coordinates heart rate, circulation, respiration

Hindbrain - Sleep, wakefulness, levels of arousal

Hindbrain - Fine motor skills

Hindbrain - Relays info from cerebellum to rest of brain – detailed function still unknown

Midbrain - Orients an organism in their environment

Midbrain - Movement and arousal, homeostatic and reflex pathways

Outermost layer of brain - divided into 2 hemispheres and 4 lobes

Gyri: The raised parts of the brain Sulci: The indentations

Bundles of axons that allow parallel parts of the brain to communicate with each other

Forebrain - Cerebral Cortex - Largest commissure

1) Frontal lobe 2) Parietal lobe 3) Temporal lobe 4) Occipital lobe

Forebrain - Cerebral Cortex - Movement, abstract thinking, executive functioning, memory, judgement - Contains Broca’s Area

Forebrain - Cerebral Cortex - Sensory input, visual processing, coordinating movement - Contains somatosensory cortex

Forebrain - Cerebral Cortex - Hearing and language - Contains Wernicke’s Area

Forebrain - Cerebral Cortex - Processes visual info

• Thalamus • Hypothalamus • Hippocampus • Amygdala • Basal Ganglia

Forebrain - Subcortical - Filters info from all major senses except for smell & relays them to the cerebral cortex

Forebrain - Subcortical - Homeostasis, blood sugar/metabolism, hunger, thirst, and sexual behavior

Forebrain - Subcortical - creates new memories and stores them long-term
