|
The Hindbrain
|
Medulla, Pons, and Cerebellum
|
|
|
Medulla
|
Regulates autonomic functioning, circulation, breathing, muscle tone, and reflexes. Cannot survive if destroyed.
|
|
|
Pons
|
Regulates sleeping, walking, and dreaming.
|
|
|
Cerebellum
|
balance and coordination of movement; analyzes sensory information; may play a role in remembering simple skills, problem solving
|
|
|
The Midbrain
|
Reticular Formation, Tectum, Tegmentum
|
|
|
Reticular Formation
|
modulates muscle reflexes, pain perception; active in states of arousal. Damage to this area may result in comas.
|
|
|
Tectum
|
involved in auditory and visual responses
|
|
|
Tegmentum
|
controls some motor functions, regulates awareness and attention and some automatic functions
|
|
|
The Forebrain
|
Thalamus, Hypothalamus, Pituitary Gland, Limbic System, Amygdala, Hippocampus, Septal Area, and Cerebrum
|
|
|
Thalamus
|
relays motor impulses out of the brain; directs incoming sensory messages to higher centers
|
|
|
Hypothalamus
|
hunger thirst, emotions, sex and reproduction, body temperature and the autonomic nervous system. (Four F's: Fighting. Fleeing. Feeding. Fucking.)
|
|
|
Pituitary Gland
|
master gland by the hypothalamus
|
|
|
Limbic System
|
loosely interconnected structures involved in emotions. No clear boundaries.
|
|
|
Amygdala
|
evaluates sensory information, linked to fear responses, emotional events
|
|
|
Hippocampus
|
formation and storage of new memories
|
|
|
Septal Area
|
pleasure area of the brain (animal increase lever pressing with impulses sent here). Lesions may create rage reactions (defensive).
|
|
|
Cerebrum
|
largest and most complex part of the brain. Divided into two halves or hemispheres. Connected by a band of fibers called the corpus callosum.
|
|
|
Occipital Lobe
|
contains the visual cortex
|
|
|
Parietal Lobe
|
somatosensory cortex; receives information about pressure, pain, touch and temperature
|
|
|
Temporal Lobe
|
involved in memory, perception, and emotion. contains the auditory cortex. Wernick's area - involved in language comprehension and processing.
|
|
|
Frontal Lobe
|
contains the motor cortex, responsible for making plans, initiative, creativity. Broca's area - involved in speech production.
|
|
|
Prefrontal Lobe (cortex)
|
involved in personality, decision making, social judgment, goal setting, sequencing, damage results in flattening of emotion and feelings.
