Wide‐Bandgap Semiconductor‐Based Neuromorphic Computing

Information &Functional Materials, Volume 3, Issue 2, Page 66-100, June 2026.
Wide‐bandgap semiconductors enable robust, low‐power neuromorphic devices for extreme environments. This review outlines material advantages, device physics, integration, and future directions for next‐generation brain‐inspired computing. ABSTRACT Neuromorphic computing has emerged as a promising paradigm to overcome the energy inefficiency and data ...

Human colour discrimination based on a non-parvocellular pathway [PDF]

Current Biology, 1996
Traditionally, colour information is assumed to be carried by neural channels in the parvocellular pathway and to be encoded in an opponent manner, while other, non-parvocellular, spectrally non-opponent channels are thought to play no part in colour vision. But is the parvocellular pathway the only way that colours can be discriminated in human vision?

Functional and structural connectivity of thalamic subnuclei in major depressive disorder at 7 Tesla

Psychiatry and Clinical Neurosciences, Volume 80, Issue 6, Page 477-489, June 2026.
Aims Major depressive disorder (MDD) is widely considered to be a mood disorder characterized by altered connectivity. The thalamus plays an important role in MDD by connecting large areas of the brain. Here, we explored thalamic connectivity in MDD at the subnuclear level using ultra‐high‐field MRI.

Foveal masking impairs orientation discrimination of peripheral low-level stimuli

Heliyon
Feedback mechanisms are common in our visual system. However, the foveal feedback hypothesis proposes a new type of non-retinotopic feedback: shape and colour information from peripheral objects is fed back to the foveal cortex.We conducted three ...

Unraveling the Dynamics of Oxytocin in Hypothalamic Neurons

Traffic, Volume 27, Issue 2, June 2026.
Oxytocin (OT) plays an important role in regulating social behavior, and dysregulation of the oxytocinergic system leads to social impairments, such as autism spectrum disorder. Central OT release is poorly understood. Using live‐cell imaging to track vesicle trajectories, combined with machine learning‐based classification, the analysis reveals ...

Pituitary Neurolobectomy induces sustained hypotension in male Wistar rats and normalizes blood pressure in male spontaneously hypertensive rats

Physiological Reports, Volume 14, Issue 11, June 2026.
Abstract Arginine vasopressin is primarily recognized as an osmoregulatory hormone; however, its contribution to vascular tone and blood pressure regulation under basal and hypertensive conditions remains debated. This study examined the effects of vasopressin deficiency induced by neurointermediate pituitary lobectomy in Wistar and spontaneously ...

Hominoid‐specific calretinin‐immunopositivity of the optic radiation (geniculocalcarine tract)

The Anatomical Record, Volume 309, Issue 5, Page 1343-1367, May 2026.
Calretinin‐immunostained coronal section through the primary (V1) and extrastriate (ExSt) cortex of the lar gibbon. Note that the optic radiation (OR) is strongly calretinin‐immunoreactive. This calretinin‐immunopositivity of the OR distinguishes the Hominoidea from other primates in terms of the neurochemistry of the OR.

Morphological differences in the lateral geniculate nucleus associated with dyslexia

NeuroImage: Clinical, 2015
Developmental dyslexia is a common learning disability characterized by normal intelligence but difficulty in skills associated with reading, writing and spelling. One of the most prominent, albeit controversial, theories of dyslexia is the magnocellular

Insulin synthesized in the paraventricular nucleus of the hypothalamus regulates pituitary growth hormone production

JCI Insight, 2020
Evidence has mounted that insulin can be synthesized in various brain regions, including the hypothalamus. However, the distribution and functions of insulin-expressing cells in the hypothalamus remain elusive.
