Neuroimaging adolescents with depression in a middle-income country: feasibility of an fMRI protocol and preliminary results

Objective: To test the feasibility and to present preliminary results of a neuroimaging protocol to evaluate adolescent depression in a middle-income setting. Methods: We assessed psychotropic medication-free adolescents (age range 14-16 years) with a diagnosis of major depressive disorder (MDD). Partic...

Neuroimaging of intrinsic connectivity networks: a robust method for assessing functional brain organization in psychiatric disorders

Alice in Wonderland syndrome: "Who in the world am I?"

Arq. neuropsiquiatr; 77 (9), 2019
ABSTRACT Alice in Wonderland syndrome (AIWS) is a paroxysmal, perceptual, visual and somesthetic disorder that can be found in patients with migraine, epilepsy, cerebrovascular disease or infections. The condition is relatively rare and unique in its hallucinatory characteristics. Objective: To discuss ...

A study on changes of the resting-state brain function network in patients with amnestic mild cognitive impairment

Braz. j. med. biol. res; 52 (5), 2019
This study aimed to explore the structural and functional characteristics of the neural network of resting-state brain activities in patients with amnestic mild cognitive impairment (aMCI) by functional magnetic resonance imaging (fMRI) technology. Resting state fMRI scanning was performed on 10 clinical...

Comparison among bone marrow mesenchymal stem and mononuclear cells to promote functional recovery after spinal cord injury in rabbits

Acta cir. bras; 32 (12), 2017
Abstract Purpose: To investigate the efficacy of allogeneic mesenchymal stem-cells and autologous mononuclear cells to promote sensorimotor recovery and tissue rescue. Methods: Female rabbits were submitted to the epidural balloon inflation method and the intravenous cells administrations were made a...

Neurobiological underpinnings of bipolar disorder focusing on findings of diffusion tensor imaging: a systematic review

Objective: To review the available data on diffusion tensor imaging (DTI) of subjects with bipolar disorder (BD), with a particular focus on fractional anisotropy (FA) in white matter (WM) tracts. Methods: The PubMed/MEDLINE database was searched for relevant articles, which were included in a systemati...

Disease association and inter-connectivity analysis of human brain specific co-expressed functional modules

Biol. Res; 48 (), 2015
BACKGROUND: In the recent studies, it is suggested that the analysis of transcriptomic change of functional modules instead of individual genes would be more effective for system-wide identification of cellular functions. This could also provide a new possibility for the better understanding of differenc...

Motivacao, vias neuronais e drogas de abuso
Motivation, neuronal pathways and drug abuse

Acredita-se que o estado motivacional de um organismo seja controlado, de modo importante, por processos reguladores homeostaticos basicos essenciais para a sobrevivencia. O hipotalamo, por suas funcoes integrativas, parece ser uma estrutura ideal do centro de controle da motivacao, assim como.......
