5-1-Genes-To-Behavior

These flashcards cover key concepts from Chapter 10 on the pathways connecting genes to behavior, including the study of neurons, neurotransmitters, and the influence of genetics on behavior.

Neurons

Specialized cells that transmit nerve impulses.

Epigenetic Control

The regulation of gene expression by environmental factors without altering the DNA sequence.

Neurotransmitters

Chemicals that transmit signals between neurons.

Action Potential

An electrical signal that travels down a neuron's axon.

Synapse

The junction between two neurons, where neurotransmitters are released.

5-HTTLPR

A gene that encodes the serotonin re-uptake transporter, influencing serotonin signaling.

Monoamine Oxidase A (MAOA)

An enzyme that breaks down neurotransmitters like dopamine and serotonin.

Feedforward Excitation

A circuit mechanism where one neuron stimulates another neuron.

Feedforward Inhibition

A mechanism where a neuron inhibits the action of another neuron.
