Position: Olfaction Standardization is Essential for the Advancement of Embodied Artificial Intelligence [PDF]

arXiv
Despite extraordinary progress in artificial intelligence (AI), modern systems remain incomplete representations of human cognition. Vision, audition, and language have received disproportionate attention due to well-defined benchmarks, standardized datasets, and consensus-driven scientific foundations.

Olfactory Signal Processing [PDF]

arXiv, 2014
Olfaction, the sense of smell, has received scant attention from a signal processing perspective in comparison to audition and vision. In this paper, we develop a signal processing paradigm for olfactory signals based on new scientific discoveries including the psychophysics concept of olfactory white.

Motor Cortex Disinhibition Correlates with Olfactory Dysfunction in Parkinson's Disease

Movement Disorders, Volume 40, Issue 6, Page 1085-1097, June 2025.
Abstract Background Motor cortex disinhibition, as measured by impaired short‐interval intracortical inhibition (SICI) using transcranial magnetic stimulation (TMS), is a well‐established feature of Parkinson's disease (PD). However, its substantial variability among patients remains unexplained, prompting questions about its origin, clinical relevance,

Anosmia and Upper Limb Rigidity—A Potential Phenotype of Idiopathic Normal Pressure Hydrocephalus with Cerebrospinal Fluid α‐Synuclein Seeds

Movement Disorders, Volume 40, Issue 6, Page 1206-1213, June 2025.
Abstract Background The pathophysiology of idiopathic normal pressure hydrocephalus (iNPH) and its association with neurodegenerative disorders is poorly understood. Objectives The aim was to determine the prevalence of α‐synuclein pathology in iNPH and its associations with clinical characteristics. Methods We used α‐synuclein seed amplification assay

Protrusion‐Derived Extracellular Vesicles (PD‐EVs) and Their Diverse Origins: Key Players in Cellular Communication, Cancer Progression, and T Cell Modulation

Biology of the Cell, Volume 117, Issue 6, June 2025.
Protrusion‐derived extracellular vesicles (PD‐EVs) driving tumor progression and immune modulation. PD‐EVs arise from dynamic cellular extensions and serve as powerful communication tools. In cancer, they reshape the tumor microenvironment, promote angiogenesis and metastasis, and modulate immune responses, including T cell activation.

Validation of the neuropathological criteria of the fourth Consortium on dementia with Lewy Bodies in autopsy cases from psychiatric hospitals

Psychiatry and Clinical Neurosciences, Volume 79, Issue 6, Page 344-355, June 2025.
Aim The pathological criteria from the fourth Consortium on Dementia With Lewy bodies (DLB) in psychiatric cohorts has not been validated. Also, the pathological differences in prodromal DLB subtypes remain unclear. This study aimed to elucidate the clinicopathological features of patients with DLB in psychiatric hospitals.

Olfactory Inertial Odometry: Methodology for Effective Robot Navigation by Scent [PDF]

arXiv
Olfactory navigation is one of the most primitive mechanisms of exploration used by organisms. Navigation by machine olfaction (artificial smell) is a very difficult task to both simulate and solve. With this work, we define olfactory inertial odometry (OIO), a framework for using inertial kinematics, and fast-sampling olfaction sensors to enable ...

Effect of body inclination on suprahyoid muscle activity during repetitive voluntary swallowing: A randomized crossover study

Physiological Reports, Volume 13, Issue 12, June 2025.
Abstract This study examined how body inclination affects swallowing dynamics by analyzing suprahyoid muscle activity during repetitive voluntary swallowing with minimal pharyngeal sensory stimulation. Fourteen healthy female volunteers participated.

Non-Markovain Quantum State Diffusion for the Tunneling in SARS-COVID-19 virus [PDF]

arXiv
In the context of biology, unlike the comprehensively established Standard Model in physics, many biological processes lack a complete theoretical framework and are often described phenomenologically. A pertinent example is olfaction -- the process through which humans and animals distinguish various odors.
