The Brain - Module 12 - Lobes & Cortex Flashcards
Cerebrum
The hemispheres that contribute 85% of the brain’s weight, neural systems within the cerebrum form specialized work teams that enable our perceiving, thinking and speaking
Cerebral Cortex
Surface layer of interconnected neural cells that covers the cerebral hemispheres, the body’s ultimate control and information-processing center
Glial Cells
Cells in the nervous system that support, nourish and protect neurons, impact learning and thinking
Frontal Lobes
Behind the forehead, involved in speaking and muscle movement - planning, complex thinking, personality, judgement, behavior, concentration, self-awareness
Parietal Lobes
At the top of head and to the rear, receives sensory input for touch and body position, processes sense of touch
Occipital Lobes
Back of the head, receives and processes information from the visual fields
Temporal Lobes
Above the ears, receiving information primarily from the opposite ear - language, sequence, organization
Motor Cortex
Rear of frontal lobes, controls voluntary movements
Somatosensory Cortex
Front of parietal lobes, registers and processes body touch and movement sensations (incoming sensations)
Visual Cortex
In occipital lobes, back of brain, visual information goes to other areas that identify words, detect emotions, recognize facts, etc.
Auditory Cortex
In temporal lobes, receives information from opposite eat
Association Areas
Areas of the cerebral cortex that are not involved in primary motor or sensory functions - involved in higher mental functions such as learning, remembering, thinking and speaking
Prefrontal Cortex
Forward part of frontal lobe, conscious brain, enables judgment, planning, and processing of new memories
Plasticity
The brain’s ability to change, especially during childhood, by reorganizing after damage or by building new pathways based on experience
Neurogenesis
The formation of new neurons
