For decades, the Basso, Beattie, and Bresnahan (BBB) open-field locomotor scale has served as the standard subjective metric for assessing hindlimb function in rodent models. However, while behavioral scales often capture substantial endogenous recovery and central pattern generator (CPG) autonomy, they frequently fail to correlate with objective neuro-electrophysiological metrics, such as motor and somatosensory evoked potentials (MEPs/SSEPs), particularly during the acute and sub-acute phases of injury. This perspective evaluates the neuroanatomical and pathophysiological mechanisms underlying this discrepancy. We dissect how the spatial distribution of contusive forces, the demyelination of anatomically spared fibers, and transient spinal shock alter early electrophysiological signaling without permanently arresting long-term behavioral plasticity. Furthermore, we highlight key neuroanatomical differences-specifically the dorsal preservation of the corticospinal tract in rodents versus the lateral architecture in humans-that complicate cross-species translation. Ultimately, we argue that relying solely on locomotor scales overestimates functional tract integrity, and we advocate for a paradigm shift toward integrating synchronized behavioral and electrophysiological profiling to improve the predictive validity of preclinical SCI trials.</p>","PeriodicalId":36527,"journal":{"name":"Neuroscience Insights","volume":"21 ","pages":"26331055261480926"},"PeriodicalIF":3.5,"publicationDate":"2026-09-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13554536/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148920021","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Additionally, it aimed to clarify how acute stress influences response inhibition, as assessed by the spontaneous recovery of operant responses following extinction, in males, females, and ovariectomized females with and without estradiol treatment. In Experiment 1, male and female rats exhibited equal rates of acquisition. While male and female rats extinguished their response also at similar rates, female rats showed transient but significantly greater extinction compared to male rats during the first day of extinction. Acute stress administered immediately prior to the extinction retention test, conducted 21 days following extinction phase, enhanced spontaneous recovery of the learned response in both male and female rats, but also led to a more rapid decline in response rates across the re-extinction session. In Experiment 2, ovariectomized female rats receiving chronic estradiol or cholesterol (control) treatment showed no significant differences in acquisition or extinction learning. Unlike Experiment 1, both estradiol-treated and non-treated ovariectomized stressed rats exhibited lower spontaneous recovery throughout the extinction retention test, indicating that naturally cycling female hormones may modulate stress effects on response recovery. Additionally, non-stressed rats treated with estradiol demonstrated reduced responding in the early stages of the extinction retention test compared to controls. These findings suggest that acute stress enhances response recovery in intact, cycling female and male rats. However, in ovariectomized female rats, acute stress attenuates the spontaneous recovery of an extinguished response in a manner partially dependent on estradiol treatment.

Our study examined the neural basis of high NaCl consumption in adult <i>Drosophila</i>, focusing on how dietary adaptation influences salt acceptance. Our findings suggest that prolonged exposure to high salt alters the taste sensitivity of the pharyngeal labral sense organ (LSO) neurons, promoting increased salt intake, particularly under starvation conditions. This modulation requires active LSO neurons, as genetic suppression of their activity in high-salt-fed flies prevents excessive salt consumption under starvation or dopamine-supplemented feeding. Furthermore, multiple independent taste receptor neurons and pathways within the LSO contribute to this response. Silencing any one of these LSO neuron types can prevent excessive salt intake.

However, the clinical use of autologous SCs is limited by donor site morbidity and challenges in large-scale expansion, leading to growing interest in human induced pluripotent stem cell (iPSC)-derived SCs. This study aimed to verify the therapeutic effects of iPSC-derived SCs in vivo and to determine whether the differentiation stage of the SCs influences their efficacy. We generated dibutyryl-cAMP-treated mature SCs and untreated immature SCs from iPSCs and transplanted them into a rat sciatic nerve crush injury model.

Myelinated axon diameter (µm) was also significantly greater in the mature SC group (4.73 ± 0.25) compared with the immature SC (4.06 ± 0.28) and control (3.86 ± 0.15) groups. Electrophysiological testing demonstrated that compound muscle action potentials in the pedal adductor muscle were detected only in the mature SC group within 28 days after surgery. Western blot analysis of the tibialis anterior muscle showed significantly higher myosin heavy chain 1 (MYH1) expression in the mature SC group than in the control group.

For each monkey, the M1 lesion volume was derived from histological sections. As a result of data extension, spontaneous recovery is represented here by individual data points derived from 14 monkeys, while data points from 8 monkeys represent therapy enhanced recovery. One therapy consisted of the administration immediately post-lesion of an anti-Nogo-A antibody (n = 4); the other treatment was a delayed autologous cellular therapy (ANCE; n = 4). The manual dexterity performance was longitudinally assessed during several years with the modified Brinkman Board task, testing the ability to grasp small food pellets from horizontal or vertical slots, using the precision grip. After M1 lesion, the grasping score dropped to zero, followed by a spontaneous, incomplete recovery in untreated monkeys, characterized by a unique plateau of recovery. In the majority of treated monkeys (n = 6), there was an additional second plateau of recovery, reflecting the effect of the treatment. Statistical non-parametric comparisons between the 14 untreated versus the 8 treated data points showed a statistically significant difference between the 2 subpopulations, based both on univariate statistics and bivariate statistics taking into account the lesion volume. This was true for recovery expressed as a degree of recuperation expressed in percent (post-lesion score/pre-lesion score × 100) as well as for the post-lesion scores only. The difference between the 2 subpopulations was more pronounced for the most difficult horizontal slots than for the less challenging vertical slots.
