Thalamus

increased gamma band activity in the thalamus promoted by deep brain stimulation and inhibition or minimization of tics and/or other symptoms of Tourette’s in both short-term and long-term evaluations. To clarify, tics are involuntary physical or verbal reactions that begin during early childhood and are characteristic of Tourette’s Syndrome. This research consisted of five patients who received Neurospace™ neurostimulator implants in the centromedian nucleus of the thalamus allowing researchers…

understanding the effects of brain damage, it is necessary to understand the brain itself, its different parts and each of their functions. The human brain is divided into three main sections, the forebrain, midbrain, and hindbrain. The cerebrum, thalamus,…

The sense of taste is not something that is unique to human. While some insect can taste things with their feet and fishes can taste with their whole body; human and other mammals are limited to their mouth. Human have 5 different types of receptor cells that responds to five primary taste: salty, sweet, sour, bitter, and umami. Human are able to interacts with the world through the peripheral nervous systems which uses nerves to connect the body’s sensory organ to the central nervous system.…

that helps coordinate movements. It helps regulate sleep and wake cycle. At the top of the brain stem is the thalamus. It is the brain’s sensory control center. Thalamus receives information from all your senses except smell. Inside the brain stem, between the ears, lies your reticular formation. These neuron network extends upward from the spinal cord through the brainstem and into the thalamus. It acts as a filter for some of the sensory messages, relaying important information to other brain…

According to Bard, the emotional response is released first, and then sent as signals by the thalamus to the brain cortex for the interpretation alongside with the sending of signals to the sympathetic nervous system or SNS to begin the physiologic response to stress. Therefore, this theory argues that emotional response to stress is not a product…

feelings. Consciousness remains constant, but can change throughout the day even if affected by certain stimuli (Sansom 2013). It relies on the brain’s ability to sort and control sensory and mental stimulation. Specifically, the cerebellum and thalamus interact to interpret the necessary information. The cerebellum is the memory of consciousness while the…

ganglia is transferred to LMNs through three different routes: the thalamus, the PPN, and the midbrain locomotor region (Lundy-Ekman, 2013, p. 235). In Huntington’s, the specific part of the basal ganglia that degenerates is the striatum, as well as the cerebral cortex. The job of the striatum is to send “inhibitory, GABA-mediated projections on to the ventral pallidum” which then brings the inhibitory output to the nucleus of the thalamus (Paradiso et al., 2008, p. 74). Because of the…

Schizophrenia Assignment This essay will be focused on a mental illness known as Schizophrenia, which Jonathon is experiencing in the Case Study. It will outline its symptoms, the brain structures of Schizophrenic patients, how neurochemistry may be a possible causative factor in it and how medication can affect the brain structure and neurochemistry to manage symptoms in diagnoses of Schizophrenia. Schizophrenia is a serious chronic mental disorder which is described chiefly by defalcation in…

of the nose where millions of sensory neurons lie on a tissue called the the olfactory epithelium. As soon as an odor molecule binds to a receptor, it sends an electrical signal the olfactory bulb, which is where the smell is identified. Then, the thalamus which is the key relation station for sensory information sends the smell information to the hippocampus and amygdala. The hippocampus and amygdala are the key brain regions involved with learning and memory. This is how the sense of smell…

The human body performs many complex processes on a daily basis it is a machine working overtime to make sure our bodies can function effortlessly and maintain homeostasis. Any disruption in the body and the body is ready to respond performing many complicated procedures to bring the human body back into balance. For example, if a person steps on a thumb tack many people would think that all that occurs is that the person feels pain and the individual jerks their leg in response due to that pain…
