1.Introduction The first tool that a child knows how to use is his own senses. Even before a baby is born, he is able to hear the voice of his mother when she speaks and when he arrives to our world; he knows when she is in the same room because he is able to […]

Communication is the process of sharing information or ideas between individuals or groups. Communication takes place in different contexts, such as phone conversations or face-to-face discussions, where information is exchanged between different locations. Similarly, within the human body, information transmission plays a vital role in decision-making and action execution. For example, when an individual touches […]

Depth perception was a puzzle to scientists and philosophers for hundreds of years. They could not understand how we can see a three-dimensional world with only a two dimensional or flat, retina in each eye. Today it is realized that the ability to perceive depth is no more amazing than any other perceptual accomplishment. We […]

Visual agnosias encompass the incapacity to visually acknowledge familiar objects, with two distinct forms: Apperceptive agnosia indicates impaired visual perception resulting in recognition challenges, while associative agnosia involves intact perceptual ability but difficulty recognizing known objects due to memory-related hindrances. Prosopagnosia, also known as associative agnosia, is a condition in which individuals are incapable of […]

What‘s the difference between science and pseudoscience? The definition of science is a “systematic knowledge of the physical or material world gained through observation and experiment” (Wikipedia. org). This definition of science seems to be based on observation of how things work, where scientist would draw up a purpose and find a method of proof. […]

In my quest for an intellectual hero in the field of Speech Language Pathology (SLP), I encountered a few limitations. Some well-known figures in this field have authored books that read more like instructional guides rather than personal accounts. However, I soon realized that not all intellectual heroes in SLP possess doctorate degrees. Often, it […]

Restoration of sight in an individual who has been blind for his entire life will not immediately result in his ability to see the things around him. It may be possible that the functional vision of this individual may have been modified due to the length of time that he has been blind. Functional vision […]

The Glasgow Coma Scale (GCS) is a numeric assessment that objectively defines the level of consciousness. A subarachnoid hemorrhage (SAH) is an intracranial bleeding stroke occurring in the space between the arachnoid and pia mater membranes on the brain’s surface, filled with cerebrospinal fluid. SAHs can be caused by cerebral aneurysm rupture, which is the […]

The perceptual system is comprised of a of a diverse range of senses including visual, auditory, olfactory and tactition; the perceptual system is part of the nervous system, which contains millions of nerve cells called receptors that sense and respond to a plethora of sensory stimuli including light, sound and temperature. The act of perceiving […]

1. The concepts of sensation and perception are frequently associated with each other. Are you capable of distinguishing the basic distinction between them? Sensation is defined as the method by which our five senses identify stimuli and convert them into neural signals. Conversely, perception relates to how we choose, structure, and decipher these unique incoming […]

Technology has been very useful for the past few years in investigating cognitive process. With the use of neuro-imaging techniques, researchers can examine brain structure and function, and thus understand better the relationship between cognition and physiology. The basic neuro-imaging techniques are the PET, the MRI, and THE fMRI scan. The PET or else the […]

One of the most common symptoms experienced after the patients undergoes periodontal scaling and root planing (SRP) is pain and discomfort. However, very little research had been conducted in the past to determine the duration and the severity of the pain. Previously, studies have been conducted to determine the severity of discomfort experienced by the […]

Studies have been conducted on cerebral lateralization and functionality of the human brain. Many studies have revealed there are no substantial differences of the left and right hemispheres of the human brain (Pinel, 2009). Some functional differences have shown one hemisphere may be slightly dominating for functional differences (Pinel, 2009). “It is widely believed that […]

The article provides detailed mechanism of how state of mind is interconnected with processes taken place in the human body.

The article is subdivided in several sections headed: introductory part providing the task of psychoneuroimmunolgy (PNI); the systems of […]

Prosopagnosia is defined as the difficulty in recognizing an individuals face; it is broken down into 3 main types; Apperceptive prosopagnosia, associative prosopagnosia and developmental prosopagnosia. Perception is an important aspect when recognizing faces, without recognizing the stimulus (face) you would not be able to identify a person. Therefore the individuals who sufferer from this […]
