This study addressed the effects of microinjections of neurotensin into the caudate nucleus and substantia nigra on the performance of motor reactions in response to positive and negative conditioned signals, as well as the post-effects of microinjections in subsequent experiments. Neurotensin had positive effects on the extinction of non-reinforced motor reactions. Neurotensin had no effect on th...... hiện toàn bộ
Role of von Economo and fork neurons in the evolution of vocal learningSpringer Science and Business Media LLC - Tập 53 - Trang 695-706 - 2023
Shubha Srivastava
The present review presents a new and feasible assumption in the comparative neurobiology of vocal production learning that underpins human speech. Vocal learning, the competence of modulating acoustic sounds or imitating novel sounds, is a requisite requirement of human spoken language and is considered a major innovation for the evolutionary origin of human verbal communication. Having numerous ...... hiện toàn bộ
The Contributions of the Right and Left Hemispheres of the Brain to the Polymorphism and Heterogeneity of Pyramidal SyndromeSpringer Science and Business Media LLC - - 2005

This study was conducted to address the clinical and neurophysiological features of pyramidal syndrome in patients with lateralized hemispheric lesions. A total of 52 patients were studied, all with hemiparesis following acute cerebrovascular accidents of the ischemic type in the right (24 patients) or left (28 patients) hemispheres of the brain. Clinical neurological analysis was performed, along...... hiện toàn bộ
Changes in the Interaction between Astrocyte Processes and Synaptic Terminals in the Generation of Epileptiform ActivitySpringer Science and Business Media LLC - Tập 50 - Trang 633-638 - 2020

The aim of the present work was to compare the structural organization of excitatory synaptic contacts in intraocular septal transplants showing normal and epileptiform activity. Experiments were performed using Wistar rats. Donor material for transplants was obtained from the septal area of the brain from 17-day-old rat fetuses. The electrophysiological properties of transplants were tested three...... hiện toàn bộ
Autism: A Diagnostic DilemmaSpringer Science and Business Media LLC - Tập 53 - Trang 34-39 - 2023
M. Zappella
The purpose of this review is to establish the reasons for the high degree of variability in the prevalence of the diagnosis of autism seen in recent decades. Significant differences in epidemiological estimates are related to the methods used in examining children with difficulties in forming relationships with other people and/or problems with communication. The present literature analysis ident...... hiện toàn bộ
