Lateral preference and longevity

Arousal mediates relations among medial paw preference, lateral paw preference, and spatial preference in the mouse.

Rodents exhibit two well-documented behavioural lateralities: spatial preference and paw preference. Waters and Denenberg [36] have identified two seemingly independent factors of paw preference: medial and lateral paw preference. In the present work, the relations among spatial preference (SP), medial paw preference (MPP), and lateral paw preference (LPP) during states of high and low arousal ...

Sweet food preference in amyotrophic lateral sclerosis

An elderly female developed anarthria with prominent emotionality over an 18month period before specialist neurological assessment. Although tongue electromyography was normal, her corticobulbar signs were consistent with amyotrophic lateral sclerosis (ALS), a pattern that, in the absence of functional impairment outside of speech and swallowing, is appropriately termed progressive bulbar palsy...

Revisiting the relationship between hand preference and lateral eye movement

The study examines the relationship between hand preference and conjugate lateral eye movements. The sample comprised of 224 persons. The hand preference was assessed using a handedness inventory. Conjugate lateral eye movements were elicited in response to verbal and spatial questions among left-, mixedand right-handers. The leftand mixed-handers exhibit significantly greater number of conjuga...

Dissociable roles for lateral orbitofrontal cortex and lateral prefrontal cortex during preference driven reversal learning

One of the archetypal task manipulations known to depend on frontal-lobe function is reversal learning, where a dominant response must be overridden due to changes in the contingencies relating stimuli, responses, and environmental feedback. Previous studies have indicated that the lateral prefrontal cortex (LPFC), the lateral orbitofrontal cortex (LOFC), the anterior cingulate cortex (ACC), an...
