How much of our life do we really have control over? This topic is covered in The Magic of the Unconscious: Automatic Brain which contemplates just how much humans are actually aware of and how much we genuinely decide. The video goes into an in-depth analysis of the automatic brain. It shows just how complicated the many processes the human brain goes through each day, in fact at every second. Humans are immensely unaware of how powerful and controlling the automatic brain is. This part of our…

INTRODUCTION A psychopath individual is known to act very impulsively, with disregard for others emotions, and against common social norms.5 Psychopathy is a mental health disorder that causes patients to exhibit lack of compassion and concern for others.2 Although there is a lot of information available to the public about how a psychopath acts, there is not much research done on why certain individuals exhibit psychopathic behaviors. Psychopaths exhibit certain characteristics and the…

processed only by the spinal cord, resulting in a fast reflex action by the body. The second pathway is known as the spinothalamic pathway where the noxious stimulus is transmitted from the spinal cord to the thalamus and finally to the somatosensory cortex in the brain. As it involves the brain this the pathway involved with pain perception.…

Parkinson’s disease is a hazardous disease and one of the most common diseases in US, about one million people live with it. It is a progressive movement disorder which means that the symptoms may get worse over time. Till now the cause is not identified or known .There is no cure but there are treatments to reduce the symptoms by medications and surgery. WHAT IS PARKINSON’S DISEASE? It is a brain disorder affecting brain cells in the brain. Parkinson’s affects neurons in an…

such extraordinary cognitive abilities, such as self-awareness, when many other species use tools, hunt, live in unstable environments, engage in group living and navigate complex social hierarchies, and perform elaborate mating displays (Flinn et al., 2005). The gorilla represents a particularly difficult anomaly for these models; despite documented tool use (Breuer et al., 2005) and social group living (Cipolletta, 2004), gorillas fail to consistently demonstrate mirror self-recognition…

part of the brain is called the cerebrum. The cerebrum is divided into two cerebral hemispheres, which develop from the forebrain. The hemispheres have the cerebral cortex which contains ten billion nerve cells. Underneath is the brainstem, and behind that is where the cerebellum is. The outermost layer of the cerebrum is the cerebral cortex is divided…

The Central Nervous System is the most important organ system in the human body because it is how we control our body. It consists of the spinal cord, nerve cells, and parts of the brain (Organ System Skit). “The nervous system takes in information through our senses, processes the information and triggers reactions, such as making your muscles move or causing you to feel pain” (How Does the Nervous System Work? NCBI). In addition, when the body wants to move, the brain sends a message to the…

single cell basis throughout hand-grasping and facial emotional expression tasks. Evidence of individual neurons that respond both to the execution of a task as well as the observation of a task is most strong in the medial frontal cortex, as well as the medial temporal cortex. This research also observed an interesting excitation and inhibition pattern at the individual cell level that they propose may act as a mechanism for maintaining a self-other distinction during both the observation and…

One of the many diseases caused by faulty cell-to-cell communication is Alzheimer’s disease. This disease causes many cells in the brain to die. Therefore, as more and more of the cells die, it causes the brain to shrink. What causes the brain cells to die, which then causes the brain to contract, is the unusual twist of the protein called tau. Tau is a protein in the brain that delivers nutrients and other important elements to the brain cells. The effect of the twisted protein inhibits the…

Positron emission tomography (PET): is an anatomically based measurement that utilizes small radioactive tracers that are able to identify and determine glucose and metabolic levels within the organs of the body. This type of tomography could be used in a concussion assessment to determine the metabolic activities and glucose levels of the brain, as these levels are important and often become altered following a concussion. Functional magnetic resonance imaging (fMRI): is an anatomically…
