Dorsal stream (Brain areas involved with consciousness)

Even at the very early stage of the retina, an important division arises between two parallel visual streams, the dorsal stream and the ventral stream. The dorsal stream projects to the parietal cortex, and is responsible for movements in relation to objects, many of them of a routine or reflex nature. It is also seen as an answer to the ‘where is it?’ location question. The processing of the dorsal is unconscious, and is faster than the consciousness-related processing of the ventral stream. Speed is adaptive for the dorsal because it has to respond to immediate developments in the external environment. Damage to the dorsal stream is shown to lead to deficits in movements and actions, rather than problems with visual perceptions. On the other hand, damage to the ventral stream results in difficulties in recognising…

Treating Motion Sickness

Motion sickness – Treatment

Introduction

For most people, motion sickness is just a minor annoyance (although it may not feel so minor at the time). The distressing symptoms of motion sickness usually stop when the motion that causes it ceases. Some travelers, however, can be incapacitated by motion sickness. There are people who suffer symptoms for even a few days after the trip is over. This is called the “mal d’embarquement” or “mal de debarquement” syndrome. (“Mal d’embarquement” is departure sickness while “mal de debarquement” is arrival sickness.)

Prevention

If you know you are prone to motion sickness or if you are suffering from it, the following is recommended: Read more…

Motion Sickness

Motion sickness

Introduction

Motion sickness (kinetosis or travel sickness) occurs when the body is subjected to accelerations of movement in different directions or under conditions where visual contact with the actual outside horizon is lost. Motion sickness is a very common disturbance of the inner ear that is caused by repeated motion such as from the swell of the sea, the movement of a car, the motion of a plane in turbulent air, etc. In the inner ear (also called the labyrinth), motion sickness affects the sense of balance and equilibrium and, hence, the sense of spatial orientation. The balance center of the inner ear then sends information to the brain that conflicts with the visual clues of apparently standing still in the interior cabin of a car, ship or airplane.

Blunt Trauma

Physical Blunt Trauma

Introduction

Blunt trauma (blunt force trauma, blunt force injury, non-penetrating trauma) refers to a type of physical trauma caused to a body part, either by impact, injury or physical attack. The term itself is used to refer to the precursory trauma, from which there is further development of more specific types of trauma, such as concussions, abrasions, lacerations, and/or bone fracturing.

Blunt trauma is contrasted with penetrating trauma, in which an object such as a bullet enters the body.

Blunt Abdominal Trauma (BAT)

Blunt abdominal trauma is often referred to as the most common type of trauma. The majority of BAT is often attributed to car-to-car collisions, in which rapid deceleration often propels the driver forwards into the Read more…

Brain Fog

Cognitive dysfunction
From Wikipedia

Cognitive dysfunction (or brain fog) is defined as unusually poor mental function, associated with confusion, forgetfulness and difficulty concentrating.[1][2] A number of medical or psychiatric conditions and treatments can cause such symptoms, including Heavy metal poisoning (in particular mercury poisoning),[3] menopause and sleep disorders (including disrupted sleep).[2]

The term brain fog is not commonly used to describe people with dementia or other conditions that are known to cause confusion and memory problems, but it can be used as a synonym for sleep inertia or grogginess upon being awakened from deep sleep.

Swollen Glands

Swollen glands
From Medline Plus, 2005

Alternative names
Swollen lymph nodes

Definition
The term “swollen glands” refers to enlargement of one or more lymph nodes. In a child, a node is enlarged if it is larger than one centimeter (0.4 inch) in diameter.

Considerations
Lymph nodes are glands that play an important part in your body’s defense against infection. They produce lymph, which travels throughout your body in the lymph system, and filters impurities from the body.

Common areas where the lymph nodes can be felt (with the fingers) include: Read more…

Complete Blood Count

CBC
From MedlinePlus Medical Encyclopedia

A complete blood count (CBC) test measures the following:

The number of red blood cells (RBCs)
The number of white blood cells (WBCs)
The total amount of hemoglobin in the blood
The fraction of the blood composed of red blood cells (hematocrit)
The mean corpuscular volume (MCV) — the size of the red blood cells

CBC also includes information about the red blood cells that is calculated from the other measurements:

MCH (mean corpuscular hemoglobin)
MCHC (mean corpuscular hemoglobin concentration) Read more…
