A man's rare tumor caused unusual nerve-related symptoms that improved after surgery.

This review discusses the causes and understanding of telogen effluvium, a form of hair loss following physiological stress, and provides no new clinical findings.

In this study, researchers found that the bioactive lipid sphingosine 1-phosphate and its receptor, S1PR3, are essential for regulating mechanical pain sensitivity in mice.

This study found that human C-tactile afferents respond to hair deflection, suggesting a functionally relevant anatomical relationship to hair follicles similar to that observed in mice.

In this study, researchers observed that P2X3-immunoreactive fibers extensively innervate the epidermis of rats, suggesting a primary role in detecting noxious stimuli in cutaneous tissue.

This study observed that methylene blue staining and zinc iodide-osmium tetroxide techniques effectively revealed anatomical details of intraepidermal nerve fibre endings in the rat's mystacial pad, suggesting their potential role in mechanoreception.

This study found that sphingosine 1-phosphate and its receptor S1PR3 are essential in regulating the acute mechanical pain response, highlighting their role in mechanonociception without affecting responses to innocuous touch or thermal stimuli.

This study reports that oxytocin receptor expression in keratinocytes shows a potential relationship with touch sensory neurons, suggesting a role in skin sensitivity and the broader function of sensory neurons.

This laboratory study concluded that TRPA1 and TRPV1 channels do not play a role in mechanotransduction processes in slowly adapting type II mechanoreceptors in isolated rat sinus hair follicles.

This study in male rats identified a unique type of mechanoreceptor, the club-like ending, which responds only to touch and not to self-motion during whisking, contrasting with other receptors that show mixed selectivity.

This study observed that innervation of the mystacial pad in rats by fine-caliber axons is more extensive and complex than previously described, with distinct differences in labeling patterns depending on the tracer and survival time.

Crickets have genetically controlled hair plates that help them sense and move their antennae.

This study found that the vermilion border and mucosa of the monkey lip have a dense sensory innervation, which correlates with their known tactile sensitivity.

The researchers reported that mast cell and nerve fiber interactions in mouse skin are highly selective for nerve fiber types and vary depending on the hair cycle phase.

This study estimates that approximately 230,000 tactile afferent fibers innervate the human body's skin, with varying densities across different regions correlating with spatial acuity and hair follicle density.

This study proposes that the terminal tuft structure in sensory nerve endings, involving Schwann cell processes and axon fingers, potentially plays a role in mechano-electric transduction in rats.

This study found that the transcription factor Meis2 is crucial for the maturation and innervation of sensory neurons responsible for light touch in mice, with its absence leading to reduced touch sensitivity.

In this study, fMRI results suggested that mechanical stimulation evoked a stronger prickle sensation comprising both pain and itch on hairy skin compared to glabrous skin.

This study found that Piezo2 channels are primarily located on sensory axon membranes in mechanosensory end organs, supporting a model where mechanical stimuli activate Aβ RA-LTMR neurons via axon protrusions.

In this study, TRPV4 channels were found in specific mechanosensory endings in mice skin, suggesting a role in pressure sensation transmitted through A- and C-fibers.

Capsaicin cream quickly relieved itching in two patients with brachioradial pruritus.

This study found that the occipital scalp had significantly higher epidermal nerve fiber density than the frontoparietal scalp, which may explain increased sensitivity in some patients.

This study found that adults with trichotillomania did not show differences in pain tolerance or exhibit analgesia to cold pressor pain compared to healthy controls.

This study found that methylene blue staining may reveal anatomical details of intraepidermal nerve fibre endings in the rat mystacial pad with greater clarity than the zinc iodide-osmium tetroxide technique.

This review examines current knowledge and treatment strategies for complex regional pain syndrome type I in adults, emphasizing clinical aspects and highlighting the lack of consensus on therapeutic approaches, without presenting new clinical findings.

This study found that Florida manatees have unique types of specialized nerve endings in their vibrissae, which assist in their sensory and manipulative functions in aquatic environments.

This study found that Cupiennius salei spiders have specialized mechanosensitive hairs on their legs that adaptively respond to joint movements during walking, suggesting a proprioceptive function.

This study investigated the dynamic mechanical properties of fluid-immersed elastic hair beds under oscillatory shear flows, revealing a nonlinear response influenced by driving frequency and amplitude, which impacts mechanosensory signaling stability in biological processes like vasodilation and ciliary remodeling.

This collection of reviews, edited by Ken Lukowiak and Janis Weeks, explores diverse sensory systems across species, including olfaction, echolocation, magnetoreception, and visual adaptations, without presenting new experimental results.

Isolation stress in rats reduces brain enzyme levels, affecting dopamine function.
