Neurons & Neurotransmitters
This part of the neuron receives incoming information from other neurons.
What are Dendrites
The brain and spinal cord make up this division of the nervous system.
What is the Central Nervous System?
This brain structure regulates essential functions such as breathing and circulation.
What is the medulla?
This type of receptor is especially important for vision in dim light
What is rods?
The tendency to group objects that are close together is called this Gestalt principle.
What is proximity?
This long, thin structure carries neural signals away from the soma.
What is the axon?
This system connects to voluntary skeletal muscles and sensory receptors.
What is the somatic nervous system
This structure connects the two cerebral hemispheres.
What is corpus callosum?
This tiny area of the retina contains only cones and provides the greatest visual acuity.
What is the fovea?
When you mentally fill in gaps in an incomplete figure, which Gestalt principle are you using?
What is closure?
These cells provide nourishment, insulation, and waste removal for neurons.
What are the glia?
Afferent neurons carry information in which direction?
What is toward the central nervous system?
This forebrain structure acts as a major relay station for sensory information, except smell.
What is thalamus?
The part of the brain's cortex where visual input ultimately arrives is located in this lobe.
What is the occipital lobe?
Processing that moves from individual elements toward the whole is called this.
What is bottom up processing?
When a neural impulse reaches the terminal buttons, these chemical messengers are released into the synapse.
What are neurotransmitters?
You're startled by a loud noise. Your heart rate increases and your body prepares for action. Which division is primarily responsible?
What is the sympathetic nervous system?
A researcher uses a technique that monitors blood flow and oxygen consumption to identify areas of increased brain activity. What technique is being used?
What is fMRI?
You stare at a brightly colored image and then look at a white wall, where you see a different color. What phenomenon is this?
What is an afterimage?
Processing that uses existing knowledge and expectations to interpret sensory information is called this.
What is top-down processing?
A student experiences muscle weakness because a chemical messenger involved in communication between motor neurons and voluntary muscles is not functioning properly. Identify the neurotransmitter.
What is acetylcholine?
After the danger passes, your body begins conserving resources and returning toward its normal state. Which division is now more active?
What is the parasympathetic nervous system?
A patient suffers damage to a brain region but later develops new patterns of neural organization that help compensate for the damage. What concept does this illustrate?
What is brain plasticity?
Someone fails to notice a clearly visible person because they are concentrating on counting basketball passes. What phenomenon does this demonstrate?
What is inattentional blindness?
Two identical lines appear to be different lengths because surrounding visual cues create a misleading impression of depth. What type of phenomenon is this?
What is a visual illusion?
