Section 3 Flashcards
Functional magnetic resonance imaging (FMRI)
Uses magnetic detectors outside the head to compare the amounts of hemoglobin with and without oxygen in different brain areas.
Hormone
Chemicals released by glands and conveyed by the blood to alter activity in various organs.
Central Nervous System
The brain and the spinal cord, communicates with the rest of the body by the Peripheral Nervous System.
Peripheral Nervous System
Nerves connecting the spinal cord with the rest of the body.
Hemisphere
Left & Right.
Controls sensation and movement on opposite side of the body.
What are the 4 lobes?
Occipital, Parietal, Temporal, & Frontal
Occipital Lobe
At the rear of the head, is specialized for vision.
Blindsight
The ability to point to or otherwise indicate the direction to a visual stimulus, without conscious perception of seeing anything at all.
Temporal Lobe
Located towards the left & right side of the head, is the main area for hearing & certain aspects of vision.
Amygdala
A structure in the temporal lobe, responds strongly to emotional situations.
Parietal Lobe
Anterior (forward) from the occipital lobe, is specialized for the body senses, including touch, pain, temperature, & awareness of the location of body parts in space.
Primary Somatosensory Cortex
A strip in the anterior portion of the parietal lobe, has cells sensitive to touch in different body areas.
Frontal Lobe
At the anterior (forward) pole of the brain, includes the Primary Motor Cortex, important for controlling fine movements, such as moving a finger or wiggling a toe.
Prefrontal Cortex
Anterior sections of the frontal lobe.
Memory of what just happened and what you are planning to do next. Also critical for decision making.
Mirror Neurons
Found in several brain areas, but especially the frontal cortex.
Active when you make a movement & also when you watch someone else make a similar movement.
