Neuroscience to Benefit from Hybrid Supercomputer Memory
Motivated by extraordinary requirements for neuroscience, IBM Research, EPFL, and ETH Zürich through the Swiss National Supercomputing Center CSCS, are exploring how to combine different types of memory – DRAM, which is standard for computer memory, and flash memory that is akin to USB sticks – for less expensive and optimal supercomputing performance. Given the [...] (Source: Neurobot)

Scientists Wire Two Rats ’ Brains Together
Scientists have reported a brain-to-brain interface (BTBI) that enabled a real-time transfer of behaviorally meaningful sensorimotor information between the brains of two rats to create a computational unit out of two brains. However, neuroscientists in the field of brain-machine interfaces (BMIs) have expressed critics on the report. The full article is available here: M. Pais-Vieira, [...] (Source: Neurobot)

Dominant-Sets clustering for spike sorting
The decision about the actual number of active neurons is an open issue in spike sorting, with sparsely firing neurons and background activity the most influencing factors. Dominant-sets clustering algorithm is a graph-theoretical algorithmic procedure that successfully addresses this issue. The quality of grouping in the data is evaluated with the estimation of ‘cohesiveness’, i.e. [...] (Source: Neurobot)

Using ISOMAP algorithm for feature extraction in spike sorting
Background noise and spike overlap pose problems in contemporary spike-sorting strategies. The (non-linear) isometric feature mapping (ISOMAP) technique reveals the intrinsic data structure and helps with recognising the involved neurons. To reproduce this tutorial in MATLAB you will need : 1. ISOMAP source code for MATLAB (for more information and updated version see here: http://isomap.stanford.edu) [...] (Source: Neurobot)
