Brain Plasticity and Communication Systems

This section covers brain plasticity and the body's communication systems, which are essential topics for AP Psychology Unit 2 vocab and AP Psychology Unit 2 quizlet study materials.

Brain Plasticity

Brain plasticity refers to the brain's capacity for modification, including its ability to reorganize after damage.

Definition: Plasticity is the brain's ability to change and adapt in response to experience or injury.

Corpus Callosum

The corpus callosum is a large band of neural fibers connecting the two brain hemispheres, facilitating interaction between them.

Endocrine System

The endocrine system is the body's "slow" chemical communication system, consisting of glands that secrete hormones into the bloodstream.

Highlight: Understanding the endocrine system is crucial for AP Psychology Unit 2 Biological Bases of behavior.

Pituitary Gland

The pituitary gland is the most influential gland in the endocrine system. It influences the hypothalamus and regulates growth and other endocrine glands.

Action Potential

Action potential occurs during neuron firing and is a key concept in understanding neural communication.

Definition: An action potential is an electrical signal that travels along the axon of a neuron, enabling communication within the nervous system.

Understanding these concepts is essential for success in AP Psychology Unit 2 review and exams.

Neural Communication and Neurotransmitters

This section focuses on the process of neural communication and the role of neurotransmitters, which is crucial knowledge for AP Psychology Unit 2 practice tests and AP Psychology Unit 2 quizlet study materials.

Threshold and Synapse

  1. Threshold: The level of stimulation needed to trigger a neural response.

  2. Synapse: The junction between the axon tip of a sending neuron and the dendrite or cell body of a receiving neuron. The tiny gap at this junction is called the synaptic gap or cleft.

Definition: A synapse is the point of communication between two neurons, where neurotransmitters are released to transmit signals.

Neurotransmitters

Neurotransmitters are chemical messengers that facilitate communication between neurons. Some important neurotransmitters include:

  1. Acetylcholine: Involved in memory and muscle contraction in the central nervous system.

  2. Endorphins: Natural neural transmitters involved in pain control and pleasure.

Definition: The nervous system is the body's electrochemical communication network, consisting of all the nerve cells of the peripheral and central nervous systems.

Key components of the nervous system include:

  1. Neurons: The basic building blocks of the nervous system.
  2. Interneurons: Neurons that communicate between sensory inputs and motor outputs.
  3. Motor neurons: Carry information from the central nervous system to muscles and glands.
