Systems neuroscience is a subdiscipline of neuroscience and systems biology that studies the function of neural circuits and systems. It is an umbrella term, encompassing a number of areas of study concerned with how neuron nerve cells behave when connected together to form neural networks . At this level of analysis, neuroscientists study how different neural circuits analyze sensory information, form perceptions of the external world, make decisions, and execute movements. Researchers in systems neuroscience are concerned with the relation between molecular neuroscience molecular and cellular neuroscience cellular approaches to understanding brain structure and function, as well as with the study of high level mental functions such as cognitive linguistics language , memory , and Consciousness Cognitive psychology and cognitive neuroscience self awareness which are the purview of behavioral neuroscience behavioral and cognitive neuroscience cognitive neuroscience . Systems neuroscientists typically employ techniques for understanding networks of neurons while they function in vivo e.g. electrophysiology single or multi electrode recording , in vivo imaging, fMRI, PET . The term is commonly used in an educational framework a common sequence of graduate school neuroscience courses consists of cellular molecular neuroscience for the first semester, then systems neuroscience for the second semester. It is also sometimes used to distinguish a subdivision within a neuroscience department at an academic institution.

Unreferenced date November 2006 About the sensory state the record company Sensory Overload Records Sensory overload sometimes abbreviated to SO , related to Cognitive load in general, is a condition where one or more of the sense s are strained and it becomes difficult to focus on the task at hand. The term is commonly but not exclusively used in the context of autistic spectrum disorder s, though it may appear in neurotypical children. It may be necessary for only one sense to be bombarded by stimulation stimuli to affect that sense as well as the other senses and the thinking process. The most common type occurs when more than one sense is stimulated. For example, a person might be watching television when someone comes in and asks a question the watcher might fail to respond because he or she simply does not register it, or realizes the question has been asked but gets confused and doesn t know whether to answer the question or concentrate on the television.

The purpose of such a provision is to provide individual and combined sensory opportunities for the user such that they may not normally experience. A sensory garden, for example, may contain features accessible to the disabled individual such as scented and edible plants, sculptures and sculpted handrails, water features designed to make sound and play over the hands, textured touch pads, magnifying glass screens, braille and audio induction loop descriptions. Depending on the user group, other provisions may integrate sound and music more centrally to combine the play needs of younger users with their sensory needs. Many sensory gardens devote themselves to providing experience for multiple senses those specialising in scent are sometimes called scented gardens , those specialising in music sound are sound gardens where the equipment doubles up to provides an enhanced opportunity for strategic developmental, learning and educational outcomes. Sensory Gardens usually have an enhanced infrastructure to permit wheelchair access and meet other accessibility concerns the design and layout provides a stimulating journey through the senses, heightening awareness, and bringing positive learning experiences.

Sensory ataxia is both a symptom and a Medical sign sign in neurology. It is a form of ataxia loss of coordination physiology coordination caused not by cerebellum cerebellar dysfunction but by loss of sensory input into the control of movement. Sensory ataxia is distinguished from ataxia cerebellar ataxia by the presence of near normal coordination when the movement in question is visually observed by the patient, but marked worsening of coordination when the eyes are closed. Sensory ataxia also lacks the associated features of cerebellar ataxia such as pendular tendon reflexes , scanning dysarthria , pathologic nystagmus nystagmus and broken pursuit eye movements. Patients with sensory ataxia often demonstrate pseudoathetosis and Romberg s sign . They usually complain of loss of balance in the dark, typically when closing their eyes in the shower or removing clothing over the head.

A stimulus physiology stimulus that is less intense than the sensory threshold will not elicit any sensation. Methods have been developed to measure thresholds in any of the senses.

Recognition threshold the level at which a stimulus can not only be detected but also recognised. Just noticeable difference Differential threshold the level at which an increase in a detected stimulus can be perceived. Terminal threshold the level beyond which a stimulus is no longer detected. Aviation use . When related to motion in any of the possible six degrees of freedom 6 DoF , the fact that sensory thresholds exist is why it is essential that aircraft have blind flying instruments. Sustained flight in cloud is not possible by seat of the pants cues alone since errors build up due to aircraft movements below the pilot s sensory threshold, ultimately leading to loss of control. In flight simulators with motion platforms, the motion sensory thresholds are utilised in the technique known as acceleration onset cueing . This is where a motion platform, having made the initial acceleration that is sensed by the simulator crew, the platform is re set to approximately its neutral position by being moved at a rate below the sensory threshold and is then ready to respond to the next acceleration demanded by the simulator computer.

See Sensory disambiguation Sensory analysis or sensory evaluation is a science scientific discipline that applies principles of experimental design and statistical analysis to the use of human sense s visual perception sight , olfaction smell , taste , touch and Hearing sense hearing for the purposes of evaluating consumer products. The discipline requires panels of human assessors, on whom the products are tested, and recording the responses made by them. By applying statistical techniques to the results it is possible to make inferences and insights about the products under test. Most large consumer goods companies have departments dedicated to sensory analysis. Sensory analysis can mainly be broken down into three sub sections Effective testing dealing with objective facts about products Affective testing dealing with subjective facts such as preferences Perception the biochemical and psychological aspects of sensation Effective testing This type of testing is concerned with obtaining ... normally be a trained panel .
