A general problem in learning is how the brain determines what lesson to learn (and what lessons not to learn). For example, sound localization is a behavior that is partially learned with the aid of vision. This process requires correctly matching a visual location to that of a sound. This is an intrinsically circular problem when sound location is itself uncertain and the visual scene is rife...

Objectives: A common concern in some cochlear-implanted children is the lack of desired progress auditory and listening skills. Such a remains despite proper verbal processor programming, additional disabilities, continuous participation hearing rehabilitation programs. more detailed assessment pathways centers processing at lower end brain stem by measuring time Electrical Stapedius Reflex (ES...

traumatic brain injury (tbi) is a common injury leading to child disability and is associated with a variety of long-term cognitive, social, and behavioral dysfunctions. emotion perception (ep) starts up an integral part of social communication is critical to achieve developmentally appropriate goals. this skill, which emerges relatively early in development, is driven by increasing connectivit...

Brain–Computer Interfaces (BCIs) have been regarded as potential tools for individuals with severe motor disabilities, such those amyotrophic lateral sclerosis, that render interfaces rely on movement unusable. This study aims to develop a dependent BCI system manual end-point control of robotic arm. A proof-of-concept was devised using parieto-occipital alpha wave modulation and cyclic menu au...

Introduction Human hearing is concerned with the perception and interpretation of sensory input to the ears. Such perception may be classiied as auditory events as opposed to sound events 5-1]. A sound event is the physical phenomenon of mechanical vibration which can characterize a sound source, while an auditory event is the brain's perception of an auditory phenomenon which may or may not be...

The Thought-Translation-Device (TTD) is a Brain-ComputerInterface (BCI) that enables completely paralyzed patients to communicate by the use of their brain signals only. Selfregulation of brain signals (e.g. the slow cortical potentials) is achieved by a feedback training. Visual impairment of these patients asks for an auditory feedback mode. The TTD can be entirely operated by combined listen...

Neuromagnetic fields were recorded from human subjects as they listened selectively to sequences of rapidly presented tones in one ear while ignoring tones of a different pitch in the opposite ear. Tones in the attended ear evoked larger magnetic brain responses than did unattended tones in the latency ranges 20-50 msec and 80-130 msec poststimulus. Source localization techniques in conjunction...

Cognitive processes are constantly under critical relevance in the field of neuroscience. In examination Electroencephalogram (EEG) data, frequency bands always significant because they determine how brain responds to various activities and circumstances different situations. However, it is usually accepted that each region associated with a certain activity, such as auditory, visual, or cognit...

Historic theories of speech perception (Motor Theory and Analysis by Synthesis) invoked listeners' knowledge of speech production to explain speech perception. Neuroimaging data show that adult listeners activate motor brain areas during speech perception. In two experiments using magnetoencephalography (MEG), we investigated motor brain activation, as well as auditory brain activation, during ...
