Lecture 6

2. Cerebrum 80 percent of brain mass Gyri and sulci
Left and right hemispheres:
Falx cerebri
Superior to cerebellum
Tentorium cerebelli
Five (six?) lobes

9. Cerebrum Caudate nucleus Olfactory bulb Basal nuclei (ganglia):
Corpus striatum (nuclei in cerebrum):
Caudate nucleus
Lentiform nucleus

10. Caudate Nucleus
Large subconscious movements of skeletal muscles.

11. Lentiform Nucleus Putamen: Globus pallidus:
Large subconscious movements of skeletal muscles.
Globus pallidus:
Regulates muscle tone.

13. Cerebral Lobes
Occipital
Parietal
Frontal
Temporal
Insula

15. Occipital Lobe Integrates eye focusing movements.
Correlates visual images with visual memory.
Involved in conscious perception of vision.
Separated from parietal lobe:
Parietooccipital sulcus

16. Parietal Lobe Somatesthetic interpretation: Understanding speech.
Postcental gyrus.
Understanding speech.
Auditory association cortex.
Wenicke’s area.
Formulating words to express thoughts and emotions.

17. Frontal Lobe Voluntary motor control: Motivation Aggression Mood
Precentral gyrus.
Motivation
Aggression
Mood

18. Frontal Lobe Personality Cognitive processes Verbal communication:
Broca’s area.

19. Temporal Lobe Receives/interprets olfactory and auditory sensations.
Responsible for storage of memory related to auditory and visual experiences.

20. Insula Not observed from surface. Involved with memory.
Psychic cortex:
Highest levels of brain function:
Abstract thought
Judgment
