Thalamus

Migraines, recurrent throbbing headaches that are typically accompanied by nausea and disturbed vision, affect fifteen percent of the world’s population (Migraine). They are particularly sensitive to any form of sound, movement, or light. Light sensitivity, otherwise known as photophobia, is often a side effect of migraines experienced by about eighty percent of migraineurs (Noseda et al 2016). “The inability to endure light can be disabling,” as said by Rami Burstein, academic director of the…

has also confirmed that emotions are linked to learning by assisting individuals in recall of memories that are stored in the central nervous system (Wolfe, 2001). Emotions originate in the limbic system and sensory information is relayed to the thalamus in the midbrain, which acts as a relay station (Wolfe, 2001). When sensory information reaches the amygdale, it is evaluated as either a threat or not, creating the fight or flight physiological response to stress (Cram & Germinario, 2000).…

amygdala and hippocampus assume crucial parts in emotions and memory. Located in the brain, the amygdala rests on either side of the thalamus and directly below the hippocampus and dictates some emotion. When damaged, emotions do not work efficiently and the creature will become indifferent to stimuli. Also located in the brain, the hippocampus lies beneath the thalamus and controls the process of changing short-term memory to long-term memory. If damaged this will inhibit the creature from…

1. Discuss what a neuron is and the functions of its basic parts (dendrites, soma, axon, myelin sheath). A neuron is a nerve cell. There are about 10,000 specific types of neurons, but there are three most common neurons: sensory, motor, and interneurons. A sensory neuron sends signals to help your brain understand what is going on around you in your environment. Sensory neurons are what make up your senses, (smell, touch, see, taste, and hear.)…

cortex of the brain is made up of the outer grey matter. Each side of the cortex has areas that represent particular regions of our body. Signals from these areas will travel to the particular areas of the body to preform specific movements. The thalamus is a structure that is very important in movement, as it is the relay station. The motor pathways are divided into two main areas, the lateral pathway and the anteriormedial pathway. The lateral pathway is responsible for voluntary…

LIMBIC SYSTEM AND TINNITUS Introduction A human body is a very delicate and complicated group of systems and organs that work together. We can say that each part of the body is controlled by and connected to several many organs. Thus, many diseases and disorders in one organ can actually indicate the error in completely different organ or system. That brings us to this, The limbic system and Tinnitus. A person who has tinnitus is a person who is continuously hear noisy and annoying voices and…

Earth, during the Reptile Age, the thalamus was developed in the brains of organisms. The thalamus is the part of the brain that deals with instinct. This includes automatic movement, like walking, and reactions, like avoiding danger or self defense. This began with the sense of smell. The thalamus would register the scents of poison, predators, or food and relate that to an instinct. When mammals came into existence, more and more layers were added to the thalamus to produce the limbic system:…

out that there are structural differences, but I was even more surprised when I realized there are three structural differences. These structural differences include the ectopias and the symmetry in the cerebral cortex and the smaller nuclei in the thalamus. Although scientists do know these structural differences have an effect on the function of the brain for a dyslexic person, they do not know the…

The speech system of the brain consists of many different brain areas (Hickok, 2012) that are entrained into stable sensory representations and motor routines through a process of constant learning (Tremblay, Houle and Ostry, 2008). Consider the simple task of producing a familiar monosyllabic word such as “head,” which presumably involves hundreds to thousands of muscle fibers and millions of neurons, and whose activity span less than 500 milliseconds (Sengupta and Nasir, 2015). Sensorimotor…

The first area of the brain to receive input from ganglion cells is the lateral geniculate nucleus of the thalamus. From there the thalamus sends information to the primary visual cortex in the occipital lobe and area V1 sends information back to the thalamus. These two areas feed information back and forth. Area V1 also sends information to the secondary visual cortex (V1) which then relays that information to different areas of…
