Chap 12: Brain Areas

Primary Motor CorteX

Allows conscious control of voluntary movements

What cells are in the Primary Motor Cortex?

Pyramidal Cells who’s axons makeup corticospinal tracts

Premotor Cortex

Helps plan movements and selects and sequences basic movements into complex task

Frontal Eye Fields

Controls voluntary eye movements

Broca’s Area

A motor speech area that directs muscles of the tongue and is active as one prepares to speaks (present in one hemisphere)

Anterior Association Area

Involved with intellect, complex learning abilities, recall, and personality

What is the Anterior Association Area necessary for?

Judgment, reasoning, persistence, and planning

Posterior Association Area

Plays role in recognizing patterns, faces, and localizing us and our surrounding space

Wernickes Area

Sounding out unfamiliar words

Broca’s Area

Speech preparation and production

Lateral prefrontal cortex

Language comprehension and word analysis

Lateral and ventral temporal lobe

Coordinate auditory and visual aspects of language

Visceral Association Area

involved in conscious perception of visceral sensation

Primary visual cortex

Receives visual info from retinas

Visual Association Area

Interprets visual stimuli (color, form, and movement)

Primary Auditory Cortex

Receives info related to pitch, rhythm, and loudness

Auditory Association Area

Stores memories of sounds and permits perception of sounds

Primary Somatosensory Cortex

Receives info from general sensory receptors proprioceptors, skeletal muscles, joints, and tendons exhibits spatial discrimination

Somatosensory Association Cortex

Integrates sensory information, comprehensive understanding of stimulus, determines size, texture, and relationship of parts
