At the age of three years‚ Jody Miller was having difficulties in moving the left side of her body and began experiencing severe epileptic seizures. She was soon diagnosed with Rasmussen’s Syndrome; a neurodegenerative syndrome including symptoms such as slight paralysis‚ epileptic seizures‚ decline in cognition and behaviour. On the recommendation of a paediatric neurologist‚ Miller underwent an operation that would remove the right hemisphere of her brain‚ known as a hemispherectomy‚ in an attempt

The Baby’s Brain: Wider Than The Sky Explain migrations-how millions of neurons travel in waves and follow cues along the way telling them exactly where to go? Neurons travel everyday in millions to carry out different task. It’s fascinating how they travel as if they are traveling across the country. They’re following cues along the way that are telling them exactly where to go. Evidence shows that young neurons have an idea about where they migrate to and can recognize their position within

thus faced with a fundamental problem: how to allow plastic mechanisms to shape their output and function‚ without compromising the stability and integrity of the underlying circuits that drive behavior. Homeostatic plasticity mechanisms that allow neurons to sense how active they are and to adjust their properties to maintain stable function Given the complexity of most central neural circuits‚ maintaining stability in function is a problem that permeates nearly every aspect of circuit development

Describe the structure of a neuron and explain the function of each of its major parts. There are five major parts of a neuron‚ the axon‚ soma‚ dendrites‚ the axon hillock and the terminal buttons. The axon transmits the neural signal. The stoma is where signals from the dendrites are joined and passed on. It serves to maintain the cell and keep the neuron functional. The dendrites help increase the surface area of the cell body. They receive info from other neurons and transmit electrical stimulation

Consists of motor neurons that innervate smooth and cardiac muscle‚ and glands; make adjustments to ensure optimal support for body activities; operate via subconscious control; also called the involuntary nervous system or general visceral motor system. 2. Preganglionic Neuron – First neuron that resides in the brain or spinal cord. 3. Preganglionic Axon – Synapses with the second motor neuron; thin‚ lightly myelinated. 4. Postganglionic Neuron – Second motor neuron. 5. Autonomic

The headache of migraine results from neurogenic inflammation of first-division trigeminal sensory neurons that innervate the large vessels and meninges of the brain. This causes a change in the way that pain is processed by the brain. Increased neuronal activity can be demonstrated in areas of the brainstem during migraine‚ and this persists even when the headache is relieved by triptans. It is not known whether this brainstem activation reflects the cause of migraine (the so-called brainstem generator)

endocrine and nervous system is at the hypothalamus. The Neuron: The Building Block of the Nervous System The nervous system is made up of nerve cells called neurons. Neuron: a nerve cell that receives processes and transmits information to other cells. The speeds in which they do so are within fractions of seconds. There are three different types of neurons‚ varying in size and shapes but have similar structure. Sensory Neurons (Afferent) - they carry information from the sense organs towards

What is Biological Psychology? It is the study of the physiological‚ evolutionary‚ and developmental mechanisms of behavior and experience. It is synonymous with the terms biopsychology‚ physiological‚ and behavioral neuroscience. Much of biological psychology is devoted to studying brain functioning. Physiology is the study of body processes- the dynamic of tissue and organ system of the body. It is the study of the physiological basis of human and animal behavior. Areas of Biological
