The interactions between memory processes and emotions are complex. Our previous investigations in the crab Neohelice led to an adaptation of the affective extension of sometimes opponent processes (AESOP) model. The mod...

Identifying the factors that promote the success of biological invasions is a key pursuit in ecology. To date, the link between animal personality and invasiveness has rarely been studied. Here, we examined in the labora...

The small ubiquitin-like modifier (SUMO), initially characterized as a suppressor of a mutation in the gene encoding the centromeric protein MIF2, is involved in many aspects of cell cycle regulation. The dynamics of con...

Alternative splicing plays critical roles in differentiation, development, and disease and is a major source for protein diversity in higher eukaryotes. Analysis of alternative splicing regulation has traditionally focus...

Autism spectrum disorders (ASDs) are neuropsychiatric diseases characterized by impaired social interaction, communication deficits, and repetitive and stereotyped behaviors. ASD etiology is unknown, and both genetic and...

It has been established that ZFP36 (also known as Tristetraprolin or TTP) promotes mRNA degradation of proteins involved in inflammation, proliferation and tumor invasiveness. In mammary epithelial cells ZFP36 expression...

Autism spectrum disorder (ASD) exhibits a gender bias, with boys more frequently affected than girls. Similarly, in mouse models induced by prenatal exposure to valproic acid (VPA), males typically display reduced sociab...

Psychostimulant addiction is associated with dysfunctions in frontal cortex. Previous data demonstrated that repeated exposure to methamphetamine (METH) can alter prefrontal cortex (PFC)-dependent functions. Here, we sho...

Animal promoters initiate transcription either at precise positions (narrow promoters) or dispersed regions (broad promoters), a distinction referred to as promoter shape. Although highly conserved, the functional proper...

Argonaute proteins have been traditionally characterized as a highly evolutionary conserved family engaged in post-transcriptional gene silencing pathways. The Argonaute family is mainly grouped into the AGO and PIWI cla...

The decision of when and how to escape result crucial for animals because it can result in an interruption to contribute to their fitness. In the present study, we analysed whether speed attack, sex and type of refuge in...

Recently (Roca et al. (2010), we used the relationship with general intelligence (Spearman’s g) to define two sets of frontal lobe or “executive” tests. For one group, including Wisconsin card sorting and verbal fl...

Starting with the contribution from psychologists like Piaget and Vygotsky to understanding psychological development the authors comment on some important recent advances in infant psychology research and confront its r...

RESUMO Este artigo tem como objetivo investigar a sinestesia na arte a partir de posicionamentos de pesquisadores, tanto das ciências cognitivas quanto do universo artístico. Do ponto de vista das neurociências, desta...

The Symbol Digit Modalities Test (SDMT) is an information processing speed test. The aim of this study was to compare the SDMT across three samples: the USA, Mexico, and Argentina. The hypothesis is that performance will...

Verbal fluency tasks are frequently used in neuropsychological assessment, standing out for their easy application and good sensitivity to early cognitive impairment. However, in Argentina, the availability of updated no...

Amacrine cells are a heterogeneous class of interneurons that modulate the transfer of the light signals through the retina. The cholinergic system present in these neurons is involved in such modulation. However, the ch...

The serotonergic system and more precisely the serotonin type 2Areceptor (5-HT2AR) is involved in a wide variety of cognitive and emotionalfunctions. In recent studies, it has been found that 5-HT2AR participates inthe p...

The α7 nicotinic acetylcholine receptor in neurons is associated to neurological and neurodegenerative disorders. α7 is also expressed in glial and immune cells, where it plays a role in neuroprotection and inflammatio...

Alpha 7 nicotinic acetylcholine receptors (nAChRs) are widely distributed throughout the central nervous system, mainly in hippocampus and cortex, and are implicated in several neurological disorders such as Alzheimer´s...
