Autonomic dysfunction

Autonomic dysfunction

Autonomic dysfunction The Autonomic (involuntary) Nervous System incorporates two branches which are the Sympathetic Nervous System (SNS) and Parasympathetic Nervous System (PNS). These branches innervate all body organs, including the cardiovascular system. The SNS and PNS help to control blood pressure and heart rate through baroreflexes/baroreceptor reflex control(1) and is understood to be responsible for […]

Case study – A rat model of long-term deficit following severe traumatic brain injury

Case study A rat model of long-term deficit following severe traumatic brain injury The ECG monitoring of exercise in Wistar rats following Traumatic Brain Injury offers insight into possible autonomic dysregulation. This case study highlights the ability to simultaneously record ECG in subjects exercising in an open pool. Matt McGuire, from the University at Buffalo […]

Case study – A dual implantation for combined Neuro and Cardiovascular recording in dog.

A dual implantation for combined Neuro and Cardiovascular recording in dog.

Case study A dual implantation for combined Neuro and Cardiovascular recording in dog Digital telemetry offers the ability to implant two transmitters in large animals, allowing to simultaneously record a large number of physiological parameters in a single subject. This case study highlights an experiment conducted by safety pharmacology team at Charles River Montreal, to […]

Behavioral studies

Behavior

Behavioral studies The study of behavior is a major element of preclinical neuroscience research. Behavioral tests are used to characterize changes in brain function that may be produced by disease, neural injury, genetic modification, drug abuse and addiction, or exposure to various agents and treatments. Our close working relashionship with Noldus Information Technology, along with […]

Traumatic Brain Injury

Traumatic Brain Injury

Traumatic Brain Injury Traumatic Brain Injury (TBI) is defined as a damage to the brain resulting from an external mechanical force. TBI is a complex disease process (Masel BE & DeWitt DS, 2010) and several studies have demonstrated that long-term functional and structural changes take place up to one year after TBI 1,2, 3. emka TECHNOLOGIES […]

Sleep disorders

Sleep

Sleep disorders Preclinical sleep research is of increasing importance, not only due to the role of sleep in memory consolidation, but also because of the link that has been established between sleep disorders and some brain or cardiovascular disorders. Indeed, sleep disturbances are a common comorbidity with neurological and cardiovascular diseases. Narcolepsy, insomnia, circadian rhythm, drug […]

Seizure & epilepsy

Seizure

Seizure & epilepsy Seizure is a disorder of the nervous system, thought to be the result of faulty electrical activity in the brain which can lead to changes in behavior, movement, feelings, and/or levels of consciousness. Epilepsy studies involve seizure detection from EEG traces, however other parameters can be of interest, such as ECG, EMG […]

Control of breathing

Control of Breathing Respiration functions through a complex network of neural controls and feedback mechanisms as the body constantly adjusts its breathing rate and tidal volume to meet respiratory metabolic demands. Several diseases and conditions disrupt the neurological and muscular signals, compromising the body’s ability to breathe normally. Neurologic and muscular disorders like Duchenne muscular […]
