Chapter II Flashcards
The study of how the brain and other aspects of the nervous system are linked to cognitive processing & behavior; discussed the anatomy (structures) and mechanisms (how it works) of the brain.
Cognitive Neuroscience
What is the main organ in Cognitive Neuroscience?
Brain
The organ in our bodies that most directly controls our thoughts, emotion and motivation.
Brain
Processes all stimuli in the environment.
Reactive
Give information to different parts of the body to tell them what to do.
Directive
Refers to the specific areas of the brain that control specific skills or behaviors.
Localization of function
The basis for our ability to perceive, adapt to, and interact with the world around us.
Nervous system
3 parts of the brain.
Forebrain
Midbrain
Hindbrain
Part of the brain that if first to develop; responsible for survival; can be seen in most animals.
Hindbrain
Parts of Hindbrain
Medulla Oblongata
Pons
Cerebellum
Part of the hindbrain that is responsible for heart activities, digestion, and swallowing; part of the brainstem; can be felt at the nape; only part that isn’t protected by the skull.
Medulla Oblongata
Part of the Hindbrain that contains neural fibers that pass signals from one part of the brain to
another; acts as bridges; all of its axons are extended to different parts of the brain for faster transportation of information.
Pons
Part of the Hindbrain that is responsible for body balance, coordination, muscle tone & procedural memory; “little cerebrum”
Cerebellum
Part of the brain that is responsible for eye coordination & eye movement.
Midbrain
Parts of Midbrain
Reticular Activating System (RAS)
Part of the midbrain that is a network of neurons essential to regulating consciousness,
including sleep; wakefulness; arousal; attention to some extent; and vital functions, such
as heartbeat and breathing; extends from midbrain to hindbrain.
Reticular Activating System (RAS)
Connects the forebrain to the spinal cord.
Brainstem
The region of the brain located toward the top and front of the brain.
Forebrain
Parts of Forebrain
Basal ganglia
Limbic system
Cerebral Cortex
Part of the Forebrain that are collections of neurons crucial to motor function; dysfunction can result in motor deficits.
Basal ganglia
Part of the Forebrain that is important to emotion, motivation, memory, and learning.
Limbic system
Organs included in the limbic system.
Hippocampus
Amygdala
Septum
Thalamus
Hypothalamus
Organ in the limbic system that is responsible for declarative memory, autobiographical memory, life experiences, memory formation, & spatial memory.
Hippocampus
A disease that produces loss of memory function.
Korsakoff ’s syndrome.
Organ in the limbic system that is an important role in emotion as well, especially in anger and aggression; perception of emotional stimuli; social cognition.
Amygdala
This is how we respond in a social environment.
Social cognition
Most important function of amygdala.
Perception of emotional stimuli
Organ in the limbic system that is involved in anger and fear.
Septum
Organ in the limbic system that relays incoming sensory information through groups of neurons
that project to the appropriate region in the cortex; acts as the switchboard; regulates sending of signals.
Thalamus
Organ in the limbic system that regulates behavior related to species survival; responsible for 4 Fs; consciousness, pressure, pain; stimulates pituitary gland.
Hypothalamus
What are the 4 Fs?
Fight
Flight
Feeding (appetite)
Fucking (mating)
Part of the Forebrain that is the outer layer of the cerebral hemispheres; plays a vital role in our thinking and other mental processes.
Cerebral cortex
In human beings, the many convolutions, or
creases, of the cerebral cortex include three elements:
Sulci
Fissures
Gyri
Small grooves
Sulci
Large grooves
Fissures
Bulges between adjacent sulci or fissures.
Gyri
2 types of cerebral cortex.
White matter
Gray matter
Interior cover of the cerebral cortex.
White matter
Grayish surface of the cerebral cortex.
