Both data sets depict electron microscopic images of the synaptic field of the hippocampal dentate gyrus of adult rats. One data set represents animals that have been trained in a learning task, the other data set represents animals that have been exposed to the same equipment but not trained i.e. passive controls. 1. Describe the general cellular components that you can identify using electron micrographs. In the images of the electron microscope that we observed, identified were mitochondria, axons

Parkinson’s Disease is a progressive disorder that affects the nerve cells in our brains that are responsible for the movement of our body. It comes slowly, so slow that you may not even notice it. But over time, a little bit of shakiness in your hand greatly impacts the way you walk, talk, sleep and even think. As this disease is something that not many people have heard of, it is one that we must be aware of as it is the second most common neurologic condition that affects about 0.3% of the population

Cerebral Palsy Cerebral palsy is " a disease which is causes sensory motor disorder as a result of incomplete brain development accompanied by problems in speech ,hearing ,sight and patterns of cognitive disorders and mental retardation"(Bobat,1980). The most patient with cerebral palsy are children. Arabian gulf are the most injured with cerebral palsy. Also, most cerebral palsy attacks occur all year round because a lot of women bring a new child and have cerebral palsy after birth or before

is one of the ways cells communicate with other cells. Endocrine signaling most naturally works with communicating with cells that are far away from each other. This long distance endocrine signaling works by releasing hormones into the circulatory system i.e., the bloodstream. For example, the pituitary gland in the brain is able to produce human growth hormone (HGH). The pituitary gland releases HGH into the bloodstream, where it will transport across the body to its receptor cells.

Generation of very small electrical fields by synaptic currents in pyramidal neurons Cross section of cortex: Afferents release glutamate, Open cation channels at pyramidal cell dendrites, only if thousands of neurons contribute their small voltage is the signal large enough to see at the scalp electrode forest for the trees. Generation of large EEG signals by synchronous activity The electric potential generated by an individual neuron is far too small to be picked up by EEG or MEG. EEG activity

Synaptic plasticity is mediated in part by postsynaptic changes that include the amount of receptors that bind neurotransmitter, types of receptors themselves, and the function of the receptors in position (Kessels and Malinow, 2009). Experience-dependent behavioral formation is expressed as the result of the change in receptor structure and function, thereby allowing synaptic strength to be altered in the brain regions controlling certain behavior types. The generation of appropriate behaviors

Material Appendix B Structures of the Nervous System This activity will increase your understanding of the different structures of the nervous system and brain. During the Web activity, you will view a variety of structures of the brain and nervous system and label each with the appropriate term. You will use this document to write a description for the terms you used in the activity. [pic] As you conduct the Structures of the Nervous System activity, follow along with this Word document

excretory, nervous, endocrine, immune, integumentary, skeletal, muscular, and reproductive systems. Though all other body systems are designed to do their own specific tasks, only one is responsible for the functioning of all other systems that are throughout the body . The nervous system is that system.The nervous system is made from two main parts. The central nervous system, that’s made up of the brain, the brainstem, and spinal cord. The other is the peripheral nervous system, which is the

Neuroanatomy is the organization and study of the nervous system. In human, the central nervous system, or CNS, includes both the structure of the brain and spinal cord. The nerves and routes the nerves take throughout the body is called the peripheral nervous system, or PNS. Central Nervous System (CNS) is the communication hub of the nervous system. It sends and receives information to Peripheral Nervous System. There are two parts of the CNS; the spinal cord and the brain (See Figure 3.) The
