A framework for a low‐cost system of automated gate control in assays of spatial cognition in fishes

Journal of Fish Biology, EarlyView.
Abstract Automation of experimental setups is a promising direction in behavioral research because it can facilitate the acquisition of data while increasing its repeatability and reliability. For example, research in spatial cognition can benefit from automated control by systematic manipulation of sensory cues and more efficient execution of training

Loss of choroid plexus‐derived insulin‐like growth factor 2 (IGF2) leads to hyposmia, while retaining post‐partum mood resilience in mice

Journal of Neuroendocrinology, EarlyView.
Abstract During the post‐partum period, new mothers are vulnerable to mood disorders. In adults, impairments in neurogenesis commonly associate with anxiety and depressive behaviors. Insulin‐like growth factor 2 (IGF2) is expressed in the choroid plexus (CP) within the subventricular zone (SVZ) neurogenic niche, and global loss of IGF2 leads to ...

Validity Examination of the Dissipative Quantum Model of Olfaction [PDF]

arXiv, 2017
The validity of the dissipative quantum model of olfaction has not been examined yet and therefore the model suffers from the lack of experimental support. Here, we generalize the model and propose a numerical analysis of the dissipative odorant-mediated inelastic electron tunneling mechanism of olfaction, to be used as a potential examination in ...

Clinical importance of olfactory function in neurodegenerative diseases

Revista Médica del Hospital General de México, 2018
Impairments in olfactory function can be potential indicators of the onset or progression of neurological disorders. Nevertheless, olfaction is barely explored in routine clinical examination.

Iranian Smell Diagnostic Test in Covid-19 Disease; Report of Covid-19 Center of North of Iran

Caspian Journal of Internal Medicine, 2022
Background: SARS-CoV-2 is a pandemic coronavirus that causes the COVID-19 syndrome. In the pandemic of COVID-19 many patients were affected to new onset olfactory dysfunction. Since there is a dearth of research studies regarding the standard smell test,

Association of impaired olfactory identification with prevalent mild cognitive impairment and regional brain atrophy: the Hisayama Study

Psychiatry and Clinical Neurosciences, EarlyView.
Aim To investigate the association of olfactory identification ability with both the prevalence of mild cognitive impairment (MCI) and regional brain atrophy in a community‐dwelling older population. Methods A total of 1293 participants without dementia aged 65 years or older underwent a Japanese version of the 4‐Item Pocket Smell Test, an assessment ...

[Olfaction in depressive disorders: Issues and perspectives].

L'Encephale, 2017
Research on sensorial interactions with psychiatric diseases and particularly with the depressive syndrome has mainly focused on visual or auditory processes and much less on olfaction. The depressive illness is one of the most frequent psychiatric diagnoses in the community, with approximately one in five women and one in eight men experiencing a ...

Genome‐wide DNA methylation profiles in the raphe nuclei of patients with autism spectrum disorder

Psychiatry and Clinical Neurosciences, EarlyView.
Aim Autism spectrum disorder (ASD) has a strong genetic basis, yet its genetic complexities remain elusive. Current research highlights environmental factors and epigenetic processes, such as DNA methylation, as crucial in ASD development. This exploratory study addresses a gap in understanding epigenetic regulation in the dorsal raphe (DR)—a region ...
