Topography of somatostatin gene expression relative to molecular progenitor domains during ontogeny of the mouse hypothalamus
2010
The hypothalamus comprises alar, basal, and floor plate developmental compartments. Recent molecular data support a rostrocaudal subdivision into rostral (terminal) and caudal (peduncular) halves. In this context, the distribution of neuronal populations expressing somatostatin (Sst) mRNA was analyzed in the developing mouse hypothalamus, comparing with the expression pattern of the genes Orthopedia (Otp), Distal-less 5 (Dlx5), Sonic Hedgehog (Shh), and Nk2 homeobox 1 (Nkx2.1). At embryonic day 10.5 (E10.5), Sst mRNA was first detectable in the anterobasal nucleus, a Nkx2.1-, Shh-, and Otp-positive basal domain. By E13.5, nascent Sst expression was also related to two additional Otp-positiv…
Brain Responses to Letters and Speech Sounds and Their Correlations With Cognitive Skills Related to Reading in Children
2018
Letter-speech sound (LSS) integration is crucial for initial stages of reading acquisition. However, the relationship between cortical organization for supporting LSS integration, including unimodal and multimodal processes, and reading skills in early readers remains unclear. In the present study, we measured brain responses to Finnish letters and speech sounds from 29 typically developing Finnish children in a child-friendly audiovisual integration experiment using magnetoencephalography. Brain source activations in response to auditory, visual and audiovisual stimuli as well as audiovisual integration response were correlated with reading skills and cognitive skills predictive of reading…
Systematic review and meta-analysis found that malnutrition was associated with poor cognitive development
2021
Aim: Malnutrition is a major public health issue that has been associated with high susceptibility for impaired brain development and mental functioning. However, to date studies on this topic have not been collated and appraised. This systematic review and meta-analysis investigated the association between malnutrition and cognitive development. Methods: We searched the MEDLINE, Scopus, CINAHL, Embase PsycINFO and Cochrane Library databases in English up to 8 December 2020. All studies reporting an association between nutritional status and cognitive development were included. p values of less than 0.05 were considered statistically significant and the results are reported as standardised …
La mente del bambino: tra lungimiranza pedagogica ed evidenze neuroscientifiche. Uno studio comparato su Maria Montessori e la Brain-based Education
2021
Il paper intende tracciare una linea di congiunzione tra le intuizioni di Maria Montessori e le recenti evidenze neuroscientifiche: “La scoperta del bambino”, auspicata dalla studiosa all’inizio del XX secolo, è tuttora in corso e punta alla conquista della comprensione del funzionamento della mente del bambino. In particolare, la riflessione si sviluppa attorno ai seguenti temi: neuroplasticità neuronale e sinaptogenesi, lo sviluppo motorio, il processo attentivo e il meccanismo della mimesi. Questi argomenti, rinvigoriti dal dialogo tra la pedagogia montessoriana e le ricerche neuroscientifiche, possono determinare un nuovo modo di intendere la questione e la prassi educativa. The paper i…
