✅ Recent studies show that it is feasible to use electrical signals from Electro-encephalography (EEG) to control devices or prostheses, these signals are provided by the body and can be measured on the scalp to determine the intent of the person when it is observing a visual stimulus frequency range detectable by the human eye.
✅ This group of signals are very susceptible to noise due to voltage levels that are able to acquire.
✅ Therefore, in this work we propose a statistical analysis of the distribution of normal EEG signals in order to determine the need of a pre-processing to remove noise components from electrical grids or other possible sources.
✅ This preprocessing includes the design and use of a filter that will eliminate any signal component that is not in the operating frequency range of the EEG occipital area of the brain.
✅ Finally, we will proceed to use the k-means algorithm to cluster with signals according to their frequency and temporal characteristics.
Perception and Encoding of Temporally Patterned Odour Stimuli in MiceInsideScientific
During this poster, Dr. Dasgupta explains his lab’s research looking at methodology and applications for analyzing the temporal structure of odour plumes. The main motivation for this research comes from theoretical postulates laid down by J.J. Hopfield (1991) suggesting that temporal structure in odour stimuli contains information about space.
Their work aims to answer the following questions:
1. Does naturally occurring odour stimulus contain temporal structure?
2. Can olfaction dependent mammals rely on temporal structure to distinguish odour stimuli?
3. Does the olfactory bulb encode temporally different odour stimulus.
Dr. Dasgupta goes on to explain how this research will help them to better understand important unsolved questions about scene segmentation and how the brain can can solve problems using olfaction.

The Brain as a Whole: Executive Neurons and Sustaining Homeostatic GliaInsideScientific
Carl Petersen and Alexei Verkhratsky share their research on homeostatic neuroglia and imaging of neuronal network function. This webinar is brought to you by APS’ new journal, Function, and part of their Physiology in Focus learning series.
During this exclusive live webinar, Carl Petersen and Alexei Verkhratsky discuss astrocyte-mediated homeostatic control of the central nervous system, and how optical and 2-photon microscopy can be used for functional neuroimaging.
Imaging Neuronal Function
Carl Petersen, PhD
Highly dynamic and spatially distributed neuronal circuits in the brain control mammalian behavior. Through technological advances, optical measurements of neuronal function can now be carried out in behaving mice at multiple scales. Wide-field imaging allows the dynamic interactions between different brain areas to be studied as sensory information is processed and transformed into behavioral output. Within a brain region, two-photon microscopy can be used to image the neuronal network activity with cellular resolution allowing different types of projection neurons to be distinguished. Together optical methods provide versatile tools for causal mechanistic understanding of neuronal network function in mice.
Astrocytes: indispensable neuronal supporters in sickness and in health
Alexei Verkhratsky, MD, PhD, DSc
The nervous system is composed of two arms: the executive neurons and the homeostatic neuroglia. The neurons require energy, support, and protection, all of which is provided by the neuroglia. Astrocytes, the principal homeostatic cells of the brain and spinal cord, are tightly integrated into the neural networks and act within the context of the neural tissue. As astrocytes control the homeostasis of the central nervous system at all levels of organization, from the molecular to the whole organ level, we can begin to define and understand brain vulnerabilities to aging and diseases.
Computational methods have complemented experimental and clinical neurosciences and led to improvements in our understanding of the nervous systems in health and disease. In parallel, neuromodulation in form of electrical and magnetic stimulation is gaining increasing acceptance in chronic and intractable diseases. First, we will present models of slow dynamics emerging on large cortical scales controlled by both subcortical networks and neurovascular coupling. The focus is on modeling migraine, though this approach is nested within the wider interest in modeling slow and large-scale dynamics in the brain. The aim is not only to better understand pain conditions and fluctuations in the resting state that causes these conditions but also to identify new opportunities to intervene with medical devices and implantable neuroprostheses. To this end, we then present the relevant state of the art of neuromodulation in migraine and approaches in fusion of both developments towards a translational computational neuroscience.
Eeg time series data analysis in focal cerebral ischemic rat modelijbesjournal
The mammalian brain exists in a number of attractors. In order to characterize these attractors we have collected the time series data from the EEG recording of rat models. The time series was obtained by recording of the frontoparietal, occipital and temporal regions of the rat brain. Significant changes have
been observed in the dimensionalities of these brain attractors between the normal state, focal ischemic
state and the drug induced state. Thus, these three states were characterized by unique lyapunov exponents,
correlation dimensions and embedding dimensions. The inverse of the lyapunov exponent gave us the long
term coherence of the rat brain and was found to differ for the three states. The autocorrelation function
measured the mean similarity of the EEG signal with itself after a time t. The degree of decay was high indicating that there was maximum correlation in the time series. Thus, the autocorrelation functions clearly indicate the effect of focal cerebral ischemia and drugs induced on the rat brain.

В мире машинного обучения многие годы доминируют нейронные сети прямого распространения (feed-forward), которые почти ничего общего не имеют с нейронами и сетями нашего мозга. В этом докладе мы познакомимся с бионическими (biologically plausible) нейронными сетями. В большинстве из них нейроны испускают и принимают импульсы (спайки). Какие возникают проблемы и сложности обучения таких сетей? В каких традиционно нерешаемых (или плохо решаемых) задачах они могут быть эффективны, как эффективен в них мозг человека и животных? Как можно реализовать такие сети аппаратно, и что такое нейроморфный компьютинг? -- Вот вопросы, которым посвящена данная презентация.
Neuron based time optimal controller of horizontal saccadic eye movementsAlireza Ghahari
A neural network model of biophysical neurons in the midbrain for controlling oculomotor
muscles during horizontal human saccades is presented. Neural circuitry that includes
omnipause neuron, premotor excitatory and inhibitory burst neurons, long lead burst neuron,
tonic neuron, interneuron, abducens nucleus and oculomotor nucleus is developed to
investigate saccade dynamics. The final motoneuronal signals drive a time-optimal
controller that stimulates a linear homeomorphic model of the oculomotor plant.

Putting the SPARK into Virtual Training.pptxCynthia Clay
This 60-minute webinar, sponsored by Adobe, was delivered for the Training Mag Network. It explored the five elements of SPARK: Storytelling, Purpose, Action, Relationships, and Kudos. Knowing how to tell a well-structured story is key to building long-term memory. Stating a clear purpose that doesn't take away from the discovery learning process is critical. Ensuring that people move from theory to practical application is imperative. Creating strong social learning is the key to commitment and engagement. Validating and affirming participants' comments is the way to create a positive learning environment.
