Flashcards in Chapter 3 Section 2 & 3 Deck (33):
outer layer of the brain. provides for better memory, more advanced social interactions, ability to experience emotions. bark-like, allows us to use language, acquire complex skills, create tools, and live in social groups
oldest and innermost region of the brain. controls basic functions of life: breathing, attention, motor responses
base of brain stem, controls heart rate and breathing
spherical shape above medulla, structure in brain stem that helps control the movements of the body, playing a particularly important role in balance and walking
long, narrow network of neurons running through medulla and pons. filters out some stimuli coming in and sends them along; also plays role in walking, eating, sexual activity and sleeping
the egg-shaped structure above the brain stem that filters even more after the reticular formation, sending some incoming stimuli to higher brain. shuts off signals during sleep
two wrinkled ovals behind brain stem. coordinates voluntary movement. influenced by alcohol.
a brain area, located between the brain stem and the two cerebral hemispheres, that governs emotions and memory. includes amygdala, hypothalamus, and hippocampus
consists of two almond-shard clusters and is primarily responsible for regulating our perceptions of and reactions to, aggression and fear
a brain structure that contains a number of small areas that perform a variety of functions, including the important role of linking the nervous system to the endocrine via the pituitary gland
two horns that curve back from amygdala. for storing long-term memories.
folding of cerebral cortex, increasing surface area
glial cells, surround and link to the neurons, protecting them and providing them with nutrients and absorbing unused neurotransmitters. myelin is an example
two main sections of brain, divided into four lobes each, each separated by folds known as fissures.
frontmost lobe, behind forehead. responsible for thinking, planning, memory, and judgement
behind frontal lobe, extends from middle to back of skull and is primarily responsible for processing information about touch.
processes visual information, at very back of skull.
between ears responsible for hearing and language`
brain is wired so that each hemispheres handles the opposite side of the bod
the part of the cortex that controls and executes movements of the body by sending signals to the cerebellum and the spinal cord
an area just behind and parallel to the motor cortex at the back of the frontal lobe, receives information from the skin's sensory receptors and movements of different body parts
the area located in the occipital lobe (very back of brain) that processes visual information
responsible for hearing and language, within the temporal lobe.
rest of cortex. areas in which sensory and motor information is combined and associated with our stored knowledge
the brain's ability to change its structure and function in response to experience or damage
the forming of new neurons.
the idea that the left and right hemispheres of the ons
connects and supports communication between two hemispheres
damage to the brain. as a result of strokes, falls, auto accidents, gunshots. studying people with lesions lets you ID what part of brain does what by studying deficiencies. part of neuroimagaing
specific neurons in visual cortex that detect movement, lines and edges, and faces
a technique that records electrical activity produced by the brain's neurons through the use of electrodes that are placed around the research participant's head
functional magnetic resonance imaging. type of brain scan that uses a magnetic field to create images of brain activity in each brain area.
