Human Brain

The human brain, containing about 10 billion nerve cells, is notable the evolutionary increase in the size and complexity of the tow cerebral hemisphere of the fore brain, relative to other brain structures. The two hemispheres are connected by a band of fibers called the corpus callosum. The limbic system is associated with memory and emotion the cerebellum controls in voluntary body functions. The thalamus, hypothalamus, and pituitary gland are all parts of the fore brain. The brain stem includes the pons and medulla oblongata and connects the rest of the brain with the signal cord.

Nerve cell or neurons, are the most complex cells in the body. The cell's control this center are of two types, the shorter dendrites an the stalklike axon. Axons of the cells in the spinal cord that convey impulses to the feet may be up to 100 cm long, but in the brain an entire neuron is usually less than 0.1 cm long. Dendrites are the pathways for receiving impulses from other cells, whereas the axon is the pathway for the impulses transmitted by the cell seen here is sheathed in an insulating membrane called myelin. Such cell make up the so-called gray matter of the brain, as opposed to unmyelinated white matter. In sheathed axons, impulses travel from one node of Ranvier to the next (areas where the sheath is interrupted); in unsheathed axons, the impulses flow continuously. The mitochondria are the cell's energy sources. Chemical substances such as the neurotransmitters that carry message to other neurons are manufactured in the rough endoplasmic reticulum and carried along the axon by the smooth endoplasmic reticulum to the nerve ending, where they are package in vesicles for transmission. Such vesicles can contain more than one kind of neurotransmitter.

Lost of Partial Memory

I just quote from question and answer of Kompas.com:

Question:.
I have just learned that my sister a few days ago, having lost her memory. Surprisingly, her memory loss, she experienced a part memory loss not absolute (or all memory is lost), only one thing missing from his memory.

He could not remember who her student fellows, are a lecturer in the faculty, principally relating to the names and faces of people he knew in his faculty.

However, my sister still remembers the lectures lesson, class schedules, remember high school friends, family, and other things. That he could not remember are peoples just in the faculty. Why it's happening dock? Is there any interference with the brain nerve or psychiatric, or else? Thank you very much for your help.

ANSWER:

What might be experienced by Iza's brother called as dissociative amnesia. This condition refers to an amnesia condition characterized by loss of memory for a particular event or events that can not be explained by a common memory loss condition.

Usually the event forgotten is a traumatic events in the past or that provide excessive stress to the person. For this case Iza's brother, seems something to do with environmental conditions related to faculty, especially faculty and friends. For that, need further examination by experts of psychiatric doctor’s alias psychiatrist.

This condition usually requires psychodynamic psychotherapy is based on analytic and can only be performed by an experienced psychiatrist. Psychiatrists are also typically able to perform hypnosis can help patients with dissociative amnesia condition.

One of the things why should psychiatrists who handle these cases because the condition of dissociative amnesia associated with cognitive and memory-related patterns of traumatic or stressful events that need to get distribution to get out or transformed into a more healthy or mature.

Brain Test

To make the test, you must prepare a blank sheet of lined paper. Every time you read a description or characteristic that applies to you, write down its number on the black sheet of paper. No certain characteristic should to choose, its depends on you. Every number on your paper, write whether it was an L or an R. Count up the number of L and R. If the number are close, that mean you use both sides of your brain equally.

Brain Lesions

Ear infections that stem from the middle ear can spread to the venous drainage of the brain, causing a brain lession or abscess. A brain abscess is a localized infection in the brain parnchyma that can develop from a collection of pus to a capsule area of infection in approximately two weeks. A brain abscess is a potentially fatal condition that can lead to death or permanent damage to the brain. Treating ear infections in the early stages with the right antibiotics helps to prevent brain lesions.

• Brain Lesion refers to any type of abnormal tissue in or on brain tissue.
• Major type of brain lesions are traumatic, infectious, malignant, benign, vascular, genetic, immune, plagues, brain cell death or malfunction, and ionizing radiation. Other chemicals and toxins have been associated with brain lesion as well.
• Brain lesions have many different causes that are related to the types listed above.
• Risk factors for the development of brain lesions include any behaviors that increase the chances a person will suffer trauma to their head, exposure to certain infections, smoking, exposure to many types of chemicals and ionizing radiation, a poor diet and alcohol use genetic risk factors are unavoidable.
• Signs and symptoms of most brain lesions are related to the type of lesion. However, some symptoms often found in patients with different types of brain lesions include headaches (recurrent or constant), nausea, vomiting, decreased appetite, changes in mood, changes in personality, behavioral changes, cognitive decline, inability to concentrate, vision problems, hearing and balance problems, muscle stiffness, weakness, numbness or paralysis, change or loss of sense of smell, memory loss, confusion, seizures, and coma.
