They bred ‘Knockout’ mice with a lower level of DISC1 in one type of neuron in the hippocampus region. They found that on a molecular level‚ the newborn ‘ knockout’ mice had neurons displaying the same characteristics such as size and shape‚ to those that were normal. When the GABA was altered to have an opposite effect‚ the neurons that

Chapter 4 Study Guide 1. What are the two main functions of the sympathetic nervous system? (A) Activating system that arouses the body‚ mobilizing its energy in stressful situations – fight/flight (B) Regulates strong emotional reactions 2. What are the two main functions of the parasympathetic NS? “Rest and Digest‚” Calming system that conserves energy. 3. How do the sympathetic and parasympathetic nervous systems work together (what are some images and metaphors used to describe them)?

Memory 1 Running head: MEMORY Memory Types Andy Doerfler Troy University Memory 2 Memory Types Memory actually takes many different forms. We know that when we store a memory‚ we are storing information. But‚ what that information is and how long we retain it determines what type of memory it is. The biggest categories of memory are short-term memory (or working memory) and long-term memory‚ based on the amount of time the memory

ROLE OF NEUROTRANSMITTERS IN LEARNING AND MEMORY – Martinez and Kesner (1991) Aim: determining the role of the neurotransmitter acetylcholine on memory Method: * Rats were trained to go through a maze and get to the end‚ where they received food * Researcher injected one group of rats with scopolamine (blocks acetylcholine receptor sites thus decreasing available acetylcholine) * Injected second group of rats with physostigmine (blocks the production of cholinesterase – cholinesterase

1. Short-term memory is the part of the memory system where information is stored for a short period of time. It is important for short term memory to exercise your brain on a daily basis. A personal experience where I had a lapse of short-term memory was when I was studying for a biology exam in the library on the 2nd floor. Then‚ another day when I went to the library‚ but sat in a different spot. I could not remember what I had remembered in the other spot. This is an example of encoding specificity

Memory and Biology There are many events in a person’s life that leave an impression or may “change” a person’s perspective or path. From birth to death the mind is recording lessons and adding to the infinite storage space known as memory. Classical conditioning Lives are filled with many lessons; some of these are learned through classical conditioning‚ operant conditioning‚ and behavioral observation. A simple example of classical conditioning would
