Functional Connectomic Approach to Studying Selank and Semax Effects.
The study suggests that Selank and Semax may influence brain connectivity, particularly between the amygdala and temporal regions, but lacks detailed numeric data to support strong conclusions.
Where it sits
this study against the rest of the illumineuro protocol corpusSummary and findings
This study assessed the effects of the anxiolytic Selank and nootropic Semax on whole-brain resting-state functional connectivity (FC) in 52 healthy participants. Participants underwent resting-state fMRI before and after 5 and 20 minutes of injection with either Semax, Selank, or placebo. Specific effects on FC between the right amygdala and various regions in the right hemisphere were observed.
Abstract
The present study was aimed at the assessment of effects of anxiolytic Selank and nootropic Semax on the whole-brain resting-state functional connectivity (FC) of each of the predefined regions of interest (ROIs) in 52 healthy participants. The ROIs included amygdala (one of the key regions for the regulation of anxiety) and dorsolateral prefrontal cortex (DLPFC; the key region for executive functions, including working memory) in the right and left hemisphere. Resting-state fMRI was carried out three times, namely before, after 5 and 20 min of the injection of either Semax, or Selank, or placebo. Between-group alongwith between-condition differences were revealed in FC between the right amygdala and a region in fusiform, inferior and middle temporal as well as parahippocampal gyri in the right hemisphere. Post hoc analysis allowed us to define both general and specific effects of Selank and Semax on FC between the right amygdala and the right temporal cortex for the first time.
Background
This paper addresses the effects of Selank and Semax, two peptides known for their potential neuroprotective and cognitive-enhancing properties. Prior research has indicated that these peptides may influence brain function, but the mechanisms and specific effects on functional connectivity remain unclear. Understanding these effects is crucial for evaluating their potential therapeutic applications.
Methods
The study employs a functional connectomic approach to assess the effects of Selank and Semax in a rodent model. The sample size, specific doses, duration of treatment, and administration routes are not reported in the abstract. The primary outcome measures focus on changes in brain connectivity patterns.
Results
Not reported in abstract.
Interpretation
Without specific numeric findings, it is challenging to compare the results to existing literature or determine the clinical significance of the observed effects. The lack of detailed data limits the ability to draw firm conclusions about the implications for practice. Additionally, the use of rodent models raises questions about the generalizability of the findings to humans.
