Psychiatry and Clinical Neurosciences, Volume 76, Issue 12, Page 620-632, December 2022., 2022 Senile depression (SD) is a heterogeneous syndrome. Several clinical profiles are more likely to appear in SD than in early‐life depression, but it remains unclear whether the pathophysiology is different. The prevalence of dementia increases with aging, and the underlying pathophysiological processes in the preclinical phase begin even before ...

Sniffing out cognitive decline in patients with and without evidence of dopaminergic deficit
Clinical Parkinsonism & Related Disorders, 2019 Background: Depletion of dopamine is a major neuropathological feature of Parkinson's disease; however, 15% of patients with parkinsonian motor symptoms have neuroimaging evidence of intact dopaminergic function.

Pest Management Science, EarlyView.Click beetle (Elateridae) olfactory preferences for plant volatiles, including those released by damaged plants, remain poorly understood. Olfactometer and electroantennography experiments revealed sex‐ and plant species‐specific olfactory preferences of Agriotes sputator beetles, with maturity influencing female responses.

Quantum effects in the brain: A review [PDF]
arXiv, 2019 In the mid-1990s it was proposed that quantum effects in proteins known as microtubules play a role in the nature of consciousness. The theory was largely dismissed due to the fact that quantum effects were thought unlikely to occur in biological systems, which are warm and wet and subject to decoherence. However, the development of quantum biology now

Recent Advances in Mammalian Olfactory Receptor Function and Structure
Sensory Neuroscience, EarlyView.Olfactory receptors (ORs), a subset of G protein‐coupled receptors (GPCRs), mediate odor detection in sensory neurons and regulate diverse physiological functions across tissues. Their roles in metabolism, immunity, and neural processes underscore their therapeutic relevance. Recent high‐resolution Cryo‐EM studies have unveiled OR activation mechanisms,

The manipulation of odor availability of training aids used in detection canine training
Frontiers in AllergyDetection canines can identify numerous substances for which they have been trained. Historically, and a point of ongoing contention, detection canine threshold (i.e., sensitivity or limit of detection) training has primarily focused on changing the ...

Computational Capacity of an Odorant Discriminator: the Linear Separability of Curves [PDF]
arXiv, 2000 We introduce and study an artificial neural network, inspired by the probabilistic Receptor Affinity Distribution model of olfaction. Our system consists on N sensory neurons whose outputs converge on a single processing linear threshold element. The system's aim is to model discrimination of a single target odorant from a large number p of background ...
