Peruvian Fur Seals as Archivists of El Niño Southern Oscillation Effects
Frontiers in Marine Science, 2021 Peru’s coastal waters are characterized by significant environmental fluctuation due to periodic El Niño- La Niña- Southern Oscillation (ENSO) events. This variability results in ecosystem-wide food web changes which are reflected in the tissues of the ...

Mechanical responses of rat vibrissae to airflow [PDF]
Journal of Experimental Biology, 2016 ABSTRACT The survival of many animals depends in part on their ability to sense the flow of the surrounding fluid medium. To date, however, little is known about how terrestrial mammals sense airflow direction or speed. The present work analyzes the mechanical response of isolated rat macrovibrissae (whiskers) to airflow to assess their ...

Learning and recognition of tactile temporal sequences by mice and humans
eLife, 2017 The world around us is replete with stimuli that unfold over time. When we hear an auditory stream like music or speech or scan a texture with our fingertip, physical features in the stimulus are concatenated in a particular order.

Learning-Dependent Plasticity of the Barrel Cortex Is Impaired by Restricting GABA-Ergic Transmission. [PDF]
PLoS ONE, 2015 Experience-induced plastic changes in the cerebral cortex are accompanied by alterations in excitatory and inhibitory transmission. Increased excitatory drive, necessary for plasticity, precedes the occurrence of plastic change, while decreased ...

Superior Colliculus Control of Vibrissa Movements [PDF]
Journal of Neurophysiology, 2008 This study tested the role of the superior colliculus in generating movements of the mystacial vibrissae—whisking. First, we compared the kinematics of whisking generated by the superior colliculus with those generated by the motor cortex. We found that in anesthetized rats, microstimulation of the colliculus evoked a sustained vibrissa protraction ...

Whisker-Mediated Touch System in Rodents: From Neuron to Behavior
Frontiers in Systems Neuroscience, 2019 A key question in systems neuroscience is to identify how sensory stimuli are represented in neuronal activity, and how the activity of sensory neurons in turn is “read out” by downstream neurons and give rise to behavior.

Tactile information from the vibrissal system modulates hippocampal functioning
Current Research in Neurobiology, 2022 Most mammals have sensory tactile hairs, also known as whiskers or vibrissae. Traditionally, whiskers are associated with diverse survival skills, including tactile discrimination, distance assessment, food acquisition, gap crossing, and social ...

Criteria for assessing peripheral nerve injury. Behavioral and functional assessment in non-operated Wistar rats [PDF]
Acta Cirúrgica Brasileira, 2020 Purpose To evaluate the normality pattern in functional tests of peripheral nerves. Methods Sixty female and sixty male Wistar rats were submitted to vibrissae movement and nictitating reflex for facial nerve; grooming test and grasping test for ...

eLife, 2017 The primary vibrissae motor cortex (vM1) is responsible for generating whisking movements. In parallel, vM1 also sends information directly to the sensory barrel cortex (vS1).

Innervation Patterns of Sea Otter (Enhydra lutris) Mystacial Follicle-Sinus Complexes
Frontiers in Neuroanatomy, 2014 Sea otters (Enhydra lutris) are the most recent group of mammals to return to the sea, and may exemplify divergent somatosensory tactile systems among mammals.
