A Local Circuit Model of Learned Striatal and Dopamine Cell Responses under Probabilistic Schedules of Reward [PDF]

open access: yes, 2007
Before choosing, it helps to know both the expected value signaled by a predictive cue and the associated uncertainty that the reward will be forthcoming. Recently, Fiorillo et al.

Assembly of the Auditory Circuitry by a Hox Genetic Network in the Mouse Brainstem [PDF]

open access: yes, 2013
Rhombomeres (r) contribute to brainstem auditory nuclei during development. Hox genes are determinants of rhombomere-derived fate and neuronal connectivity.

Loss of Sympathetic Nerves in Spleens from Patients with End Stage Sepsis

open access: yesFrontiers in Immunology, 2017
The spleen is an important site for central regulation of immune function by noradrenergic sympathetic nerves, but little is known about this major region of neuroimmune communication in humans.

Neuroprotective effects of ursodeoxycholic acid in Parkinson's disease and Alzheimer's disease

open access: yesNeuroprotection, EarlyView.
In Parkinson's disease (PD) and Alzheimer's disease (AD), various shared pathological mechanisms exist. UDCA has been shown to exert neuroprotective effects in preclinical and clinical studies. Such effects include the mitigation of neuroinflammation as well as rescue effects on mitochondrial dysfunction, oxidative stress, impaired autophagy, and ...

Evolution and Development of the Inner Ear Efferent System: Transforming a Motor Neuron Population to Connect to the Most Unusual Motor Protein via Ancient Nicotinic Receptors

open access: yesFrontiers in Cellular Neuroscience, 2017
All craniate chordates have inner ears with hair cells that receive input from the brain by cholinergic centrifugal fibers, the so-called inner ear efferents (IEEs). Comparative data suggest that IEEs derive from facial branchial motor (FBM) neurons that

Cholinergic Fibers and Muscarinic Receptors in the Central Auditory System

open access: yesThe Journal of Kansai Medical University, 2012
アルツハイマー病では中枢聴覚系の機能障害を示唆する症状を合併する場合が少なくない.また細胞変性等の病変が疾病脳の聴覚上行路各部位にも確認されている.本研究ではマウス脳のこれらの部位におけるコリン線維とムスカリン性受容体(m2,m3タイプ)の発現分布密度を測定した.聴覚上行路諸核で,これらコリン線維・受容体を介する情報伝達・変換が聴覚の伝達に一定の意義を有することが,本研究から強く示唆された.

Implantable Brain–Machine Interface for Olfactory Neural Regulation in Bioelectronic Nose: A Review

open access: yesSensory Neuroscience, EarlyView.
The olfactory Brain‐Machine Interface described in this paper bypasses damaged peripheral olfactory pathways by implanting stimulation electrodes in the olfactory bulb or higher‐order olfactory cortex, thereby forming a closed‐loop system that integrates signal acquisition, information decoding, and cortical integration.

Exploring the Impact of Polystyrene Microplastic Beads on Male Gonads of the Marine Mussel, Mytilus galloprovincialis

open access: yesEnvironmental Toxicology, Volume 41, Issue 7, Page 379-394, July 2026.
ABSTRACT Plastic, with its remarkable versatility and numerous applications, has greatly benefited humanity. However, its extreme resistance to natural degradation means it persists in the environment for long periods, causing global environmental problems.
