Synapse

Automated measurements of mitochondrial transport in hippocampal and cortical neurons. Mitochondria are transported to synapses by kinesin motor proteins. We have recently described methodologies for the automated analysis of fast mitochondrial transport from data acquired using a robotic microscope. We focused on addressing questions of measurement precision, speed, reliably

adolescents are still learning how to properly perform these actions. During adolescents there is an increase in grey matter, then a peak around midway, and then a decrease. This is caused by the increase in synapses by learning new things. The decrease is caused by the strengthening of synapses that are used often and the removal of ones that are not. This way the prefrontal cortex is “pruned” (Blakemore). The prefrontal cortex also inhibits risk taking but because it is still developing in adolescents

Chapter III: The Science of Cannabis: Nature and Effects Before we start studying in detail the effects of Cannabis on human nervous system, we need to understand a few details about the Endocannabinoid system. The effects of Cannabis are due to the fact that there are receptors in our brain which allow certain active molecules found in Cannabis to bind to those sites. These receivers are called Cannabinoid receptors and the many different cells and tissues which allow Cannabinoids to bind to them

fact. All of your long term memories you know and live like your name, family, how to speak, how to walk, and all those memories are stored in the cerebellum, basal nuclei, and motor cortex. To make long term memories you send a neuron signal to a synapse you then build

Stimulants, sometimes called “uppers,” temporarily increase alertness, attention, and energy, as well as elevate blood pressure, heart rate, and respiration.  Methamphetamine is a illegal drug in the form of white crystalline.It has the names of meth, crank, chalk and speed . IT can be taken by snorting , smoking, orally or injecting with a needle. It can develop a strong desire to continue using it because it creates a false sense of happiness and well confidence, hyperactiveness and energy and

Alexis-Marie Robinson Mrs Reilly English III Honors Period 6 09 Of March 2015 How A Person’s Memory Works Memory is a concept that refers to the process of remembering. Recalling memories uses the same neurological paths humans use originally to sense the experience-which in result, almost recreates the event. Researchers believe memory is a brain-wide process, meaning that memory is not restricted to one area of the brain. Scent is one of the strongest senses tied to memory. Humans receive information

The Nervous System The nervous system is the most complex part of the body, as they govern our thoughts, feelings, and bodily functions. It is an important factor in science because it can lead to new discoveries for cures or diseases. The studies of the nervous system helped lower death rates from heart disease, stroke, accidents, etc. The nervous system is a network of neurons (nerve cells) that that sends information to the brain to be analyzed. Neurons live both in and outside the central nervous

Regulatory Behavior Emily Beecher PSY/340 April 27, 2015 Dr. Annie Powers Regulatory Behavior The nervous system is an extremely elaborate biological machine. Without question, the nervous system is a system so intricate and comprehensive that professionals in the field of medicine to this day do not have a “complete picture” of each of the working details of the human nervous system. Of these different mechanisms, perhaps the one most riddled with speculation, is the mechanism of sleep. In discussing

According to Alzheimer.net, forty-four million people, worldwide, are diagnosed with Alzheimer’s disease. In the United States, one out of nine people over the age of 65 are diagnosed with this disease, and it ranks as the sixth leading cause of death in the United States. Two out of three people diagnosed with Alzheimer’s are women. Five point three million dollars are depleted every year from citizens diagnosed with Alzheimer’s. Alzheimer’s is “a progressive and fatal disease of the brain” (Lu

restore it to its resting potential (Martini et al. pp. 408-409). These action potentials developed by the stimulus are carried by the axons of the sensory neurons to the CNS. The information carried by the action potentials is processed at every relay synapse, and is sent to the multiple nuclei and centers in spinal cord and brain (Martini et al. p. 510). In the brain, the general somatic sensory information is relayed to the Primary Somatosensory Cortex neurons. The Premotor Cortex (Somatic Sensory Association
