So, what makes someone be considered an adult when they grow up? When they’re 18, 25 or when they’re above 18, but they’re fully mature before the age of 25. So why do people say the age should be 18, even though there are many 18 year olds who are considered an “adult” but still don’t make the right decisions for themselves and can’t even take care of themselves? Same goes for 25, why should that age be considered an adult? Well the most reasonable answer to determine adulthood is when they’re…

The stigma of mental illnesses has been a constant struggle for teenagers with any kind of mental disorder. The average age of onset of mental health disorders is 14 years; anxiety disorders, bipolar disorder, depression and eating disorder. Psychosis and substance abuse almost all emerge during adolescence (Paus 6). The way society perceives these mental illnesses has improved because of neuroscience, as it has provided scientific evidence that they aren’t “faking” it. With the improvement of…

and is responsible for regulating breathing rate and depth, co-ordination, eye movement, taste, facial expression and balance. The pons varolii acts as a bridge joining the cerebrum to the medulla oblongata and cerebellum and also joins the two hemispheres of the cerebellum to…

When I read what happens when your hippocampus is damaged, my mind went to a movie I just watch. In 50 first dates Drew Barrymore plays a woman who can’t form new memories because she was in a crash in which she received a head injury. We can assume from the movie that she has injured her hippocampus. Since her hippocampus was damage it cause her to have ametrograde amnesia which means she can no longer make new long term memories since the crash. This is occurring because the switching station…

No one knows for certain exactly what causes migraines. Currently it is thought a series of small irritations or events build up until the dam bursts and a migraine headache is triggered. What causes migraines, or triggers them, varies from individual to individual. What affects one person won't have the slightest affect on others. Migraine triggers are very personal. The experience of many who suffer from these headaches is that a particular food or mix of foods will tip them over the edge into…

The amygdala is often called the “aggression center” of the brain. There are two of them in one’s limbic system, and they are located on either side of the thalamus, at the end of the hippocampus, a little bit in front of the brain stem. When the amygdalas are stimulated, one feels anger, violence, fear, and anxiety. When the amygdalas are completely destroyed, a person has what is called Kluver-Bucy syndrome. The effects of this syndrome include hyperorality, hypersexuality, and…

subthalamus is below the hypothalamus. “The thalamus is a vital structure lying deep within the brain that has several important functions. There are extensive nerve networks that send signals all around the structures of the brain including the cerebral cortex. The thalamus is involved in sensory and motor signal relay and the regulation of consciousness and sleep” (Mandal). Sensory messages that travel to the thalamus come from the senses of the body such as seeing, hearing, tasting, touch,…

Abstract: There are no “typical” manifestations of symptoms when it comes to cerebral palsy. Cerebral palsy is a non-progressive motor disorder caused by congenital or acquired brain damage. It is difficult to say with any certainty what kind of struggles a child with CP will have. This is due to the great variability of how CP manifests. Cerebral palsy symptoms can range in severity and impact any number bodily processes and systems. The effect of CP on speech subsystems is no different, and…

Cerebral Palsy Sometimes we take our everyday actions for granted. People living with Cerebral Palsy don?t have this luxury. In fact, they are forced to carefully monitor their activities and limit themselves due to their inability to perform certain tasks. Cerebral Palsy is not one particular disease, it is actually a term used to cover a wide variety of disorders: Spastic, Dyskinetic, Atheoid, Atoxic and Mixed Presentation Cerebral Palsy. The most common of these is Spastic Cerebral Palsy. An…

motor cortex area to have decrease activity because of the increase inhibition from the thalamus causing decrease activity to the lateral corticalspinal and rubrospinal tracts. The result of this change is impairment of voluntary movement creating symptoms of such as akinesia and bradykinesia. The next part of the motor loop to be affected is the increase inhibition pedunculopontine nucleus causing disinhibition of the reticulospinal tract causing rigidity of postural and girdle…
