Axon

The child's experiences are the stimulation that sparks the activity between axons and dendrites and creates synapses” (Sara Gable,2001). Therefore, we can say that nature partner is nurture, the environment surroundings that influence infants and toddler’s development. Babies understandings in their environment will affect all…

brain is that various neurons are sending information to one another concerning what you are thinking, sensing or doing. It is at the level of this inter-neuron communication that most drugs have their effects”. These neurons have three parts: the axon, the nucleus and something called dendrites. All three of these send and receive messages in the brain; neurotransmitters are what send the…

Maria D. Rodriguez Investigation of the potential TNT transmission of α-syn between neurons in PD pathogenesis A.SPECIFIC AIMS Parkinson’s disease (PD) is defined on a molecular level as an abnormal level of Lewy-body formation, as well as the loss of dopamine-producing neurons in the substantia-nigra in the midbrain . The major protein component found in Lewy-bodies is α-synuclein. This protein is most commonly found in synaptic clefts of neurons in the brain. In familial cases, the excess…

The choroidal arteries are deep cerebral arteries that supply deep structures in the brain. The anterior choroidal artery is a branch of the internal carotid and it supplies the choroid plexus in the lateral ventricles, parts of the visual pathway, the putamen, the thalamus, and the hippocampus. The posterior choroidal artery is a branch of the posterior cerebral artery. It supplies blood to the choroid plexus of the third ventricle and parts of the thalamus and hippocampus. An occlusion of…

Its 6am; the alarm goes off. This time Jack doesn 't scream or cover his ears. The once familiar feeling of each sound wave as they hit the sides of his skull; the agonizing echo bouncing in his head is gone. To many, noting this absence in response seems extreme; perhaps an exaggeration or overly dramatic, but to Jack, it 's a moment he never understood before. For him it 's the moment of knowing what it feels like to be "normal"; even if it 's just for this one time. Reaching this monumental…

Neurons are only a subset of the billions of cells in our brain, but they are the powerhouse driving everything we do. Common genetic and cellular properties define them as neurons. Beyond these defining features, neurons are heterogeneous in there gene expression, shape, and role in driving behavior (cite Zeisel et al. 2015 and Kamme et al 2003). Even within very homogenous populations such as the pyramidal CA1 neurons, there is significant variation in neuronal properties. This leads to…

The use of cameras or recording devices in policing is not a new concept, but with the use a new variation of the technology and a new application for it requires new policies and procedures to ensure the best outcome of the use of body-worn cameras. Many of the large police services across North America have begun their own pilot program to determine the effectiveness of the body-worn cameras and how they are best used. Also, there is the factor of cost associated with funding these projects.…

As an adult, we will face uncountable instances of stress or frustration. While certain amounts of stress are considered normal, excessive stressful situations can take a toll on our overall health. Extensive research has been done to show the detrimental effects that stress can have on the body. It can affect sleep habits, the digestive system, heart rate, blood pressure, and can even exacerbate preexisting health problems. Numerous medical and psychological research studies show significant…

Essay question 6: Nicholas Carr’s book “The Shallows” argues that the internet is not only shaping our lives but physically altering our brains. Do you agree or disagree with this claim? The internet has revolutionised communication to an extent where it has made many social, cultural and economic changes. The digital world we live in has transformed the way we live, think and communicate. The internet has radically changed our world; it is an essential need in everybody's life, without it we…

organ control functions and higher center within the brain that control more information processing. The peripheral nervous system is subdivided into two nerves, the autonomic system, and the somatic system. These nerves are made up of bundles of axons and found outside of the brain and spinal cord. Sensory nerves of the peripheral system contain sensory receptors that detect changes within the internal and external environment. Symptoms of stress on the nervous system includes; headaches, heart…
