Issue 2.6 of Brain and Behavior is now freely available online!
The latest issue of Brain and Behavior is now live! The journal publishes research articles across all areas of neurology, neuroscience, psychology and psychiatry. The cover features an image from Isolated CNS Whipple disease with normal brain MRI and false-positive CSF 14-3-3 protein: a case report and review of the literature by Victor W. Sung, Michael J. Lyerly, Kenneth B. Fallon and Khurram Bashir: “Brain tissue showing the bacteria responsible for causing CNS Whipple disease, Tropheryma whipplei, present both within macrophages (right) and free in the neuropil (left).” We have 13 excellent papers in this issues, all of which are fully open access.
Below are two top articles highlighted by our editorial team:
Cellular basis for singing motor pattern generation in the field cricket (Gryllus bimaculatus DeGeer) by Stefan Schöneich and Berthold Hedwig.
Abstract: The singing behavior of male crickets allows analyzing a central pattern generator (CPG) that was shaped by sexual selection for reliable production of species-specific communication signals. After localizing the essential ganglia for singing in Gryllus bimaculatus, we now studied the calling song CPG at the cellular level. Fictive singing was initiated by pharmacological brain stimulation. The motor pattern underlying syllables and chirps was recorded as alternating spike bursts of wing-opener and wing-closer motoneurons in a truncated wing nerve; it precisely reflected the natural calling song.
BDNF Val66Met polymorphism interacts with sex to influence bimanual motor control in healthy humans byRuud Smolders, Mark Rijpkema, Barbara Franke and Guillén Fernández.
Abstract: Brain-derived neurotrophic factor (BDNF) plays a critical role in brain development. A common single nucleotide polymorphism in the gene encoding BDNF (rs6265, Val66Met) affects BDNF release and has been associated with altered learning and memory performance, and with structural changes in brain morphology and corpus callosum integrity. BDNF Val66Met has more recently been shown to influence motor learning and performance. Some of the BDNF effects seem to be modulated by an individual’s sex, but currently the relationship between BDNF and sex in the motor domain remains elusive. Here, we investigate the relationship between BDNF Val66Met genotype and an individual’s sex in the motor system.
