Term
What are the three major parts of your brain?
Definition
• the cerebrum, the cerebellum and the brain stem.
Term
What is the function of the cerebrum?
Definition
The largest of the three brain sections accounts for about 85 percent of the brain's weight, and contains the largest of the three brain sections, accounts for about 85 percent of the brain's weight, and has four lobes
Term
What is the function the cerebellum?
Definition
The region controls voluntary movement and thought
Term
What is the function the brain stem?
Definition
• connects the spinal cord and the brain. It controls functions that keep people alive such as breathing, heart rate, blood pressure and food digestion. Those activities occur without any thought.
Term
What are the four lobes of the brain?
Definition
frontal, parietal, temporal and occip
Term
What is the function of the parietal lobe?
Definition
helps people understand what they see and feel.
Term
What is the function of the frontal lobe?
Definition
determines personality and emotions.
Term
What is the function the occipital lobe?
Definition
Where vision functions are located.
Term
What is the function the temporal lobe?
Definition
Where Hearing and word recognition abilities are located.
Term
At what age do doctors generally agree the brain stops growing?
Definition
During the first three years of life, the brain experiences most of its growth and develops most of its potential for learning
Term
What is synapto genesis?
Definition
The creation of pathways for brain cells to communicate which occurs during brain development.
Term
How do Inhalants, such as glue, paint, gasoline and aerosols, impact the brain?
Definition
They destroy the outer lining of nerve cells and make them unable to communicate with one another.
Term
How does marijuana impact the brain?
Definition
It hinders memory, learning, judgment and reaction times, while steroids cause aggression and violent mood swings.
Term
How does Ecstasy impact the brain?
Definition
It has been found that drug destroys neurons that make serotonin, a chemical crucial in controlling sleep, violence, mood swings and sexual urges.
Term
What are neurons?
Definition
The basic functional units of the nervous system.
Term
What are the neuron parts?
Definition
They are the nerve cell body, axon and dendrite
Term
What occurs when the neuron parts rapidly fire?
Definition
Thought turns into movement.
Term
What is a nerve synapse?
Definition
The space from one nerve cell to the next nerve cell.
Term
What are neurotransmitters?
Definition
Chemicals that help to carry impulses across the synapse
Term
What is the focus of the "old brain" ?
Definition
regulates basic survival functions,breathing, moving, resting, and feeding, and creates our experiences of emotion.
Term
Mammals, including humans, have developed further brain advanced brain functions—for instance, better memory, more sophisticated social interactions, and the ability to experience emotions. Humans have a very large and highly developed outer layer known as the ______________, which makes us particularly adept at these processes.
Definition
cerebral cortex
Term
brain stem
Definition
is the oldest and innermost region of the brain. It's designed to control the most basic functions of life, including breathing, attention, and motor responses
Term
medulla
Definition
the area of the brain stem that controls heart rate and breathing.
Term
pons
Definition
a structure in the brain stem that helps control the movements of the body, playing a particularly important role in balance and walking.
Term
reticular formation
Definition
a long narrow network of neurons running through the medulla and the pons.
Term
thalamus
Definition
is the egg-shaped structure above the brain stem that applies still more filtering to the sensory information that is coming up from the spinal cord and through the reticular formation, and it relays some of these remaining signals to the higher brain levels
Term
cerebellum
Definition
consists of two wrinkled ovals behind the brain stem. It functions to coordinate voluntary movement.
Term
limbic system
Definition
is a brain area, located between the brain stem and the two cerebral hemispheres, that governs emotion and memory. It includes the amygdala, the hypothalamus, and the hippocampus.
Term
amygdala
Definition
consists of two "almond-shaped" clusters (amygdala comes from the Latin word for "almond") and is primarily responsible for regulating our perceptions of, and reactions to, aggression and fear
Term
hypothalamus
Definition
is 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 system via the pituitary gland
Term
hippocampus
Definition
consists of two "horns" that curve back from the amygdala. It is important in storing information in long-term memory
Term
cerebral cortex
Definition
the outer bark-like layer of our brain that allows us to so successfully use language, acquire complex skills, create tools, and live in social groups. Humans have a larger one which sets us apart from other animals
Term
corticalization
Definition
the folding of the cerebral cortex which allows for greater surface area and size increasing capacities for learning, remembering and thinking in humans
Term
cerebral cortex
Definition
It is only about one tenth of an inch thick, it makes up more than 80% of the brain's weight. Contains 20 billion nerve cells and 300 trillion synaptic connections.
Term
glial cells (glia)
Definition
billions of cells that surround and link to the neurons, protecting them, providing them with nutrients, and absorbing unused neurotransmitters.
Term
cerebral cortex
Definition
is divided into two hemispheres, and each hemisphere is divided into four lobes, each separated by folds known as fissures.
Term
contralateral control
Definition
The brain is wired such that in most cases the left hemisphere receives sensations from and controls the right side of the body, and vice versa.
Term
motor cortex
Definition
the part of the cortex that controls and executes movements of the body by sending signals to the cerebellum and the spinal cord.
Term
The brain has ______ sensory receptors, these patients feel no pain
Definition
no
Term
somatosensory cortex
Definition
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 the movements of different body parts. Again, the more sensitive the body region, the more area is dedicated
Term
visual cortex
Definition
is the area located in the occipital lobe (at the very back of the brain) that processes visual information
Term
auditory cortex
Definition
which is responsible for hearing and language
Term
association areas
Definition
in which sensory and motor information is combined and associated with our stored knowledge. This is involved in higher mental functions, such as learning, thinking, planning, judging, moral reflecting, figuring, and spatial reasoning.
Term
Neuroplasticity
Definition
refers to the brain's ability to change its structure and function in response to experience or damage. It enables us to learn and remember new things and adjust to new experiences.
Term
neurogenesis
Definition
the forming of new neurons
Term
brain lateralization
Definition
the idea that the left and the right hemispheres of the brain are specialized to perform different functions.
Term
corpus callosum
Definition
the region that normally connects the two halves of the brain and supports communication between the hemispheres
Term
The left hemisphere
Definition
is also better at math and at judging time and rhythm. It is also superior in coordinating the order of complex movements—for example, lip movements needed for speech.
Term
The right hemisphere
Definition
is able to recognize objects, including faces, patterns, and melodies, and it can put a puzzle together or draw a picture.
Term
About ____ of people are mainly right-handed, whereas only ____ are primarily left-handed.
Definition
90%, 10%
