Here’s a knowledge organizer I’ve created of the most essential concepts for neurons and the structure of the nervous system in an introductory psychology course. These knowledge organizers are designed to help you identify the most important factual knowledge you … Read More
Long-Term Potentiation (LTP)
In this video I explain the concept of long-term potentiation, which refers to the strengthening of neural connections due to repeated synchronous firing. Repeated firing leads to changes in chemical signaling between the two neurons, influencing neurotransmitter and receptor activity. … Read More
How Hearing Works: Parts of the Ear
In this video I explain the process of transduction for hearing in order to convert soundwaves into neural activity. I describe each of the parts of the ear and discuss how the movement of fluid in the basilar membrane triggers … Read More
Drugs and Neurotransmitters: Agonist or Antagonist?
In this video I discuss some ways that drugs can influence the functioning of neurotransmitters by binding to receptors on postsynaptic neurons. I explain the difference between agonist drugs which increase effects of a neurotransmitter and antagonist drugs which reduce … Read More
Introduction to Neurotransmitters
In this video I introduce several neurotransmitters including acetylcholine, dopamine, GABA, serotonin, and norepinephrine. I also describe some of the functions of each of these neurotransmitters, with the caveat to avoid oversimplifying the role of neurotransmitters in explaining complex behaviors. … Read More
What Happens to Neurotransmitters After Release?
In this video I explain what else can happen to a neurotransmitter after release (besides binding to a receptor on the postsynaptic neuron). These include reuptake, enzyme deactivation, and autoreception, and I provide mnemonics for remembering each of these processes. … Read More
How Neurons Communicate: The Synapse
In this video I explain how two neurons communicate using a neurotransmitter that travels across the synapse to receptor sites. This neurotransmitter can then influence the flow of ions in the postsynaptic neuron which can change its likelihood of firing … Read More
The Action Potential
In this video I explain how an action potential is triggered in a neuron when it reaches its threshold. I explain the movement of ions, resting potential, and the all or none principle of neural firing. I also cover how … Read More
Neuron Structure: Parts of a Neuron
In this video I describe the major parts of a neuron and briefly explain the function that each part serves. Don’t forget to subscribe to the channel to see future videos! Have questions or topics you’d like to see covered … Read More
Biological Bases of Behavior – Resources
On this page you’ll find a number of resources for understanding the biological approach to psychology as well as concepts of genetics and heritability. If I’ve missed a good resource, please share it in the comments section! General Resources Biological Bases … Read More
