Genetics and Behavior

Circadian Rhythm

• The natural, internal process that regulates the sleep-wake cycle and other physiological processes.

• A type of sleep disorder characterized by excessive daytime sleepiness.

• A method of measuring time based on the position of the sun.

• A psychological condition affecting mood and behavior.

Cones

• Photoreceptor cells in the retina that are responsible for color vision and function best in bright light.

• Cells in the retina that detect motion and are more sensitive in low light.

• Neurons that transmit visual information from the retina to the brain.

• Photoreceptor cells that are primarily responsible for peripheral vision.

Substance Use Disorder

• A condition characterized by an individual's inability to control their use of a substance despite negative consequences.

• A temporary increase in tolerance to a substance after prolonged use.

• A psychological condition that only affects individuals with a family history of addiction.

• A phase of experimentation with substances that does not lead to dependency.

Split Brain Research

• Studies involving patients with severed corpus callosum to understand the functions of each hemisphere.

• Research on the effects of brain injuries on cognitive functions.

• Investigations into the impact of language on brain development.

• Experiments analyzing the relationship between brain size and intelligence.

Depolarization

• The process during the action potential when the cell membrane becomes more positive.

• The process of the cell membrane becoming more negative during an action potential.

• The phase where the cell is at rest and not transmitting signals.

• The process of neurotransmitter release at the synapse.

Action Potential

• A neural impulse that travels down an axon, triggered by a change in electrical charge.

• A chemical signal that transmits information between neurons.

• A type of electrical signal that only occurs in the brain.

• A process that inhibits the firing of neurons.

Trichromatic Theory

• A theory of color vision that proposes three types of cones sensitive to red, green, and blue light.

• A theory that suggests color vision is based on the mixing of primary colors only.

• A theory that states color perception is determined by the brightness of light.

• A theory that explains color vision through the interaction of rods and cones.

Biological Psychology

• The study of the relationship between biological processes and psychological phenomena.

• The examination of social influences on behavior.

• The analysis of cognitive processes in decision making.

• The exploration of emotional responses to environmental stimuli.

Excitatory Neurotransmitters

• Neurotransmitters that decrease the likelihood of a neuron firing an action potential.

• Neurotransmitters that increase the likelihood of a neuron firing an action potential.

• Neurotransmitters that inhibit the release of hormones.

• Neurotransmitters that have no effect on neuron activity.

Marijuana

• A psychoactive drug derived from the Cannabis plant, often used for recreational or medicinal purposes.

• A type of alcohol used in cocktails.

• A synthetic drug used to treat anxiety disorders.

• A natural herb used for cooking.
