Flipped instruction using online enrichment is a popular way to enhance active learning in the laboratory setting. Graduate student teaching assistants at University of California, Irvine flipped an upper division undergraduate neurobiology and behavior lab using the new online software platform "" The following research study compares the impact of pre-lab online instruction (front flipping) and post-lab online instruction (back flipping) on student exam performance. We describe a novel method for unbiased categorization of exam questions by degree of difficulty.

These benefits occurred without changes in human α-synuclein pathology and were mediated in part by stem cell-induced elevation of brain-derived neurotrophic factor (BDNF). However, instrastriatal NSC transplantation likely alters the brain microenvironment via multiple mechanisms that may synergize to promote cognitive and motor recovery.

However, whether social interaction or novel physical stimulation is responsible for this recovery is controversial. In the current study, we have investigated the effects of only social enrichment (SocE) in progressively MPTP-lesioned mice.

In addition to exploratory and somatosensory behavior, motor skills that are thought to be directly translatable to human Parkinson's disease patients are assessed. However, many of these motor tests require the training and learning of particular tasks, so it cannot be determined whether impairments are due to motor or to learning deficit.

We determined the extent of dopamine (DA) terminal changes using Western immunoblotting [striatal dopamine transporter (DAT) and tyrosine hydroxylase (TH)] and alterations in the mean number of DA cells/section by immunohistochemistry and Nissl staining [TH-labeled cells and thionin-stained cells in the substantia nigra pars compacta (SN-PC)]. We measured recovery of gait performance and amount of spontaneous physical activity using the parallel rod activity chamber (PRAC).
