Anatomy of afferent visual pathway
Acta Ophthalmologica, 2013AbstractThe afferent visual pathway encodes and transmits all aspects of image perception from retina to occipital lobe. A critical feature of this pathway is the topographic organization of the fibers that make up the afferent visual pathway. Knowledge of the anatomy and topography of the afferent visual pathway will aid recognition and localization ...

The Vasomotor Centre and its Afferent Pathways
Clinical Science, 19741. Experiments were carried out on two groups of anaesthetized greyhounds. The response of the first group to infusions of angiotensin II into a vertebral artery for 5 min and to bilateral occlusion of the common carotid arteries for 2 min was studied before and after bilateral ablation of the areas postrema.

Afferent and Efferent Pathways
Abstract The autonomic nervous system (ANS) is divided into not only sympathetic and parasympathetic divisions, but afferent and efferent pathways as well. Afferent fibers transmit sensory information from the periphery to higher centers, while efferent fibers transmit modulate responses from the central nervous system back to the ...Simranjit Singh +1 more

Afferent neural pathways in cough and reflex bronchoconstriction
Journal of Applied Physiology, 1988Cough and bronchoconstriction are airway reflexes that protect the lung from inspired noxious agents. These two reflexes can be evoked both from the larynx and tracheobronchial tree and also from some extrarespiratory sites. Within the airways, certain sites are particularly sensitive to stimulation of cough (larynx and points of proximal airway ...

Afferent visual pathways in multiple sclerosis: a review
Clinical & Experimental Ophthalmology, 2016AbstractMultiple sclerosis (MS) is a disease of the central nervous system that involves inflammation and demyelination at multiple sites and causes a wide variety of clinical presentations with variable neurological deficits. The visual pathways are frequently involved with either visual or motor dysfunction. Optic neuritis (ON) is one the most common

Evaluation of afferent pain pathways in adrenomyeloneuropathic patients
Clinical Neurophysiology, 2018Patients with adrenomyeloneuropathy may have dysfunctions of visual, auditory, motor and somatosensory pathways. We thought on examining the nociceptive pathways by means of laser evoked potentials (LEPs), to obtain additional information on the pathophysiology of this condition.In 13 adrenomyeloneuropathic patients we examined LEPs to leg, arm and ...

Spinal afferent pathway of the tactile placing reaction
Experientia, 1960Die exterozeptive Aufsetzreaktion der Hinterpfote der Katze nach verschiedenartigen Ruckenmarksverletzungen ist untersucht worden. Nach Entfernung des Hinterstranges bleibt dieselbe erhalten, sie verschwindet nach oberflachlicher Verletzung im medialen dorsalen Teil des Seitenstranges. Es wird angenommen, dass eine in diesem Ruckenmarksteil verlaufende

Afferent pathways for autonomic and shivering thermoeffectors
2018Body core temperature of mammals is regulated by the central nervous system, in which the preoptic area (POA) of the hypothalamus plays a pivotal role. The POA receives peripheral and central thermosensory neural information and provides command signals to effector organs to elicit involuntary thermoregulatory responses, including shivering ...

Central pathways relaying cardiovascular afferent information to amygdala
American Journal of Physiology-Regulatory, Integrative and Comparative Physiology, 1985It has been suggested that cardiovascular information to the amygdala is relayed through the paraventricular nucleus of the hypothalamus (PVH) and the parabrachial nucleus (PB;7). To test this possibility spontaneously firing units in the amygdala of 12 chloralose-anesthetized cats were monitored for changes in firing frequency during electrical ...

Effect of sodium hydroxybutyrate on afferent pathways
Pharmacological Research Communications, 1971Abstract The present investigation is devoted to the study of the influence of sodium hydroxybutyrate on the potentials of the cortex and some subcortical structures, evoked by electrical stimulation of somatic and visceral nerves as well as by acoustic and light stimulation.
