How does sending a signal from one neuron to another work?
- neurotransmitters are flowing into the synapse to the other neuron
- some of the neurotransmitters reach the postsynaptic neuron
- the cel membrane of the postsynaptic neuron contains receptors, which are specific so only certain neurotransmitters can fit into specific receptors.
- when a neurotransmitter fits into a receptor site, a message can be sent to the postsynaptic cell.
- sometimes messages are excitatory, sometimes inhibitory
What happens to neurotransmitters that don't reach the postsynaptic neuron?
- reuptake; some neurotransmitters are taken back into the presynaptic cell.
- what remains in the synapse is broken down by enzymes.

How do we call the elimination of synaptic connections during adolescence?
What concept is central to the body's response to stress?
How does the HPA axis work?
- when people are faced with threat, the hypothalamus releases corticotropin-releasing factor CRF.
- CRF communicates with the pituitary gland.
- the pituitary gland releases adrenocorticotopic hormone which travels to the adrenal glands
- the adrenal cortex promotes release of cortisol. often referred to as the stress hormone.
How do we call the concept that operates automatic an controls the endocrine glands, and muscles around the blood vessels, stomach, intestines, kidneys, and other organs?
How do we call the field that studies how psychological factors impact the immune system?
What are the characteristics of the natural immunity system?

- getting attention
- generating sensory feedback
- gaining access to desirable things or situations
A problem with reinforcing desired behavior is that it can't continuously be reinforced forever. how is this problem overcome?
intermittent reinforcement makes desired behavior more enduring

attachment theory
What theory stresses the importance of long-standing patterns in close relationships, particularly within the family, that are shaped by the ways people think and feel?
What is the thought of the attachment theory?
How do we call a treatment that emphasizes the importance of current relationships in a person's life, and how problems in these relationships can contribute to psychological symptoms?
How does interpersonal therapy (ITP) work?
- the therapist encourages the patient to identify feelings about his relationships and express these feelings.
