Description

Aim:

Reproducibility is critical to scientific inquiry, which relies on the independent verification of results. Progress in science also requires that we determine whether conclusions were obtained using a rigorous process, and we must know whether results are robust to small changes in conditions. Computational approaches present unique challenges for these requirements. A foundational research work in the computational neuroscience field, published in the last years, will be replicated by means of up-to-date models, in order to verify the results claimed by the original authors.

Project phases:

– Literature study about important neuroscience foundational papers.
– Identification of the target problem to replicate
– Development of the verification pipeline and appropriate codes (e.g. Spiking Neural Networks with NEST simulator)
– Analysis of the results and comparison with the original claims

Description

Aim:

Neural decoding is a critical step in BCI technologies. Different machine learning algorithms have been used to guide neural prosthetic limbs but results are far to get close at the natural body performance. In the last years, the availability of multi-electrode array system equipped with more and more recording channels is requiring a big data approach necessary. Together with the rising in computing power, the artificial neural networks (ANN) are a promising tool to address neural decoding problem. We propose to take advantage of modern ANN implementations to decode motor intentions from neural data recorded from behaving monkeys. Exploring different ANN architectures, the aim is to increase decoder robustness and reliability to be effectively implemented in clinical neuroprosthesis.

Project phases:

– Literature research
– Implementation of the ANN architecture
– Data analysis
– Interpretation and discusion of the results

Description

Aim:

During tasks and actions of humans and animals, neuronal populations communicate using a complex interplay of transient oscillatory rhythms. Neural signals generated by the activity of neuronal populations also display this type of transient behavior. This makes non-stationary spectral analysis of neural signals using wavelet functions a useful tool to investigate neural activity.

Wavelet–based techniques are suitable for this type of signals since they possess one key property called multiresolution. Multiresolution allows to accurately determines low frequency components and simultaneously localize time rapidly transient events.

Here, we propose to analyze extracellular signals recorded from multi-electrode array implanted in the posterior parietal area of monkeys during reach-to-grasp and reach-to-target task. Specifically, we will consider the low frequency part (< 300 Hz) of the extracellular field, called Local Field Potential (LFP). LFPs will be analyzed using wavelet-based techniques, such as Continuous Wavelet Transform and Wavelet Coherence to determine which type of scales (frequencies) characterizes the different tasks both at single and multi-electrode levels. This is a key step in the decoding of neuronal population dynamics for brain-machine-interfaces and biomedical applications

Description

Aim:

Voice signals provide important information to measure human behaviors and cognitive functions. Various types of neurodegenerative dementia (Alzheimer’s disease, frontotemporal dementia, primary progressive aphasia, Lewy body dementia) affect human speech in different manners. Disorders or irregularities in language domain, evaluated in terms of temporal features, such as pauses, speech rate, pitch, etc, could be strong predictors of different neurodegenerative pathologies affecting the brain. This thesis aims at the development and validation of a software tool able to automatically extract a set of language features sensitive and to classify neurodegenerative disorders from voice signals.

Project phases:

Starting from a Matlab-algorithm to automatically extract voice features from recordings and a dataset of recordings on healthy elderly subjects:

– Literature review on vocal indicators of cognitive decline
– Creation of a database of normal and pathological voice samples from elderly (control subjects, patients with Alzheimer’s disease, frontotemporal dementia, primary progressive aphasia and Lewy body dementia)
– Optimization of the algorithm to extract voice features
– Development of a classification algorithm to support the diagnosis of neurodegenerative diseases based on voice features and neurodegenerative biomarkers (magnetic resonance atrophy, cerebrospinal fluid proteins concentration)

Description

Aim:

The complex figure of Rey-Osterreith ( ROCF ) is a neuropsychological test largely used for the diagnosis of dementia and Alzheimer’s disease. It requires the subject to copy, by hand, the ROCF and the accuracy of the drawn image provides useful information on the location and severity of a brain damage. However, the scoring methods of the ROCF test are currently performed by clinicians in what tends to be a subjective manner, which is open to interpretation and leads to a poor inter-rater reliability. 

This thesis project aims at developing an end-to-end expert system which automates the visual analysis of the ROCF and helps operators in the neurological assessment of patients, by returning the most probable diagnosis from a digitized version of the ROCF drawn by the subject. This is a retrospective study in which data (ROCF drawings) are collected from paper-based patient records, scanned, and labelled according to the respective patient’s diagnosis.

Project phases:

Creation of a database containing labeled ROCFs
Definition of the expert system’s specs and requirements, according to clinicians
Definition of the classification problem(s)
– Data preparation
– Design and implementation of the expert system based on deep learning classificators

Requirements:
