Brain Development Length The human body it’s in a constant change and development, physical and intellectual development from the conception until it dies. Besides the heart, the brain is considered the most important organ of our body. The brain starts its development from the nine to sixteen week of gestation and it continues growing and improving through the time and experiences. The brain development starts very fast in the infancy and becomes slower through the lifespan. In the first months…

In this episode of The Nature of Things, multiple techniques are explained by Dr. Norman Doidge, that help to improve the function of brain; allowing for better injury recovery. This study includes treatments for, severe causes of autism, traumatic brain injury recovery, Parkinson’s, and a girl missing one-third of her cerebellum. Specifically, these treatments include light treatment, sound treatment, using other brain regions to complete everyday tasks, and passing electrical currents through…

that there are two neural pathways of the brain function and they are the high road and low road thinking. The difference between these two ways is, high road thinking is a slow and deep- level thinking by using the new brain as known as the cerebral cortex to think of the logic, sequential, non-emotional, conscious and verbal communication. However, low road thinking is using the old brain (amygdala) as known as a limbic system to process emotions, holistic, non-verbal communication,…

Marijuana is a very controversial topic in today’s society. Everybody from local potheads, to priests, are talking about marijuana. Researchers have studied the psychological effects of marijuana on an adolescents’ (14-17) and adult’s brain, such as their impulsivity, attention, memory and decision making. Hypothesis Ultimately because marijuana is such a controversial topic, researchers have decided to study marijuana and its lasting effects, mostly on adolescents, because “one out of ten teens…

When the body becomes exposed to chronic exposure to alcohol the body will adapt to changes thus causing different responses to it. A person that drinks alcohol all the time will build up a tolerance to alcohol and will not get the effect as a person that drinks once and while or rarely drinks. The brain will start to develop a pathological craving for alcohol, longer the chronic drinker uses alcohol the stronger the desires become to fulfill them. If the body does not get the desired fix of…

The main three sections of the brain are the hindbrain, the limbic system, and the cerebral cortex. The hindbrain consists of the medulla which is directly above the spinal cord and controls breathing, heartbeat, and other vital life functions like the things we don’t have conscious control over. It also has pons which are in the uppermost level…

patterns of the upper motor neurons. The cerebellum receives its input from the spinal cord in form of mossy fibers that project from the pons and spinocerebellar pathways. Mossy fibers contribute the information necessary for the output from the motor cortex and sensory information about the state of the body. In addition, it also receives input from climbing fibers that project from the inferior olive, of which contribute information about the errors in movement. These climbing…

Anatomy of cerebral cortex: Brain is most complex organ in human body. The ability of brain for its functioning normally is manifestation of various activities it takes participation in various activities of day to day life, being it hidden from the view or perceptible, like walking, smelling, thinking, laughing, speaking, and hearing. These manifestations are results of very coordinated and complex electrical and chemical activity within and between the cells those makes up our brain. Abnormal…

human behavior is linked, somehow or someway, to the brain’s functions. According to the beliefs of these psychologists, each area of the brain influences different thinking and behavior. For example, language in humans is controlled by the cerebral cortex, but it contains two separate subsections. Broca’s area controls the production of speech and Wernicke’s area controls the comprehension of speech. Apart from the individual roles parts of the brain play, one’s behavior is also linked to the…

stabilise the joint (Schultz RA et al1984). Injuries, including ACL tears, are likely to disrupt this process. Spinal motor neuron receives afferent information from both ipsilateral and contralateral limbs (Cuadrado ML et al 1999). In the cerebral motor cortex cross-connections between…
