Abstract:

In the last decades, electrochemistry has been regarded as a powerful tool to address some of the key challenges that in the framework of sustainability and green energy. In particular, the application of smart, hierarchical materials as electrocatalysts is generating new opportunities for interesting developments. Nanostructured carbon has been heavily employed as a fundamental component for the proposed catalytic materials due to its outstanding electronic and textural properties. This thesis focuses on the exploitation of strategically designed materials based on carbon as electrocatalysts

Abstract:

Processing of sensory input requires information transfer between neurons primarily via action potentials. The interaction between synaptic input and the ionic mechanisms of action potential generation leads to stereotyped sequences of action potential events. It is hypothesized that these spike sequences code for the sensory inputs. Spike trains often consist of sequences of single action potentials and clusters of action potentials or bursts. Investigations in this thesis are directed toward identifying candidate coding mechanisms in the processing of electrosensory input by pyramidal cells

Abstract:

Effective exploration of the environment is a critical aspect of adaptive behaviour, enabling animals to identify food sources, potential mates, refuge locations, and other important resources. The particular strategies used during exploratory behaviours depend on a variety of factors including context, personality traits and natural ecology. Weakly electric fish rely specifically on a short-range electric sense to search and locate objects in their environment in low-light conditions. However, little is known about the exploratory strategies used. We characterized the exploratory movements o

Abstract:

Underwater electrosense, manipulating underwater electric field for sensing purpose, is a growing technology bio-inspired by weakly electric fish that can navigate in dark or cluttered water. We studied its theoretical foundations and developed sophisticated sensing algorithms including some first-introduced techniques such as discrete dipole approximation (DDA) and convolutional neural networks (CNN), which were tested and validated by simulation and a planar sensor prototype. This work pave a solid way to applications on practical underwater robots.

Abstract:

Gamma-frequency burst discharge in pyramidal cells of the apteronotid electrosensory lateral line lobe (ELL) is necessary for signal processing. Bursting is dependent on an interaction between somatic and apical dendritic currents, in which spike broadening in the apical dendrite potentiates a somatic afterpotential that follows each rapid somatic spike. Somatic spike repolarization must be consistent in order for the afterpotential to be expressed soon after. The work presented in this thesis describes how the expression and differential subcellular distribution of two Kv3-type K+ channels in

Abstract:

Most sensory systems need to discriminate between wide ranges of behaviorally relevant signals. In order to achieve this, neurons need to adjust their response properties, such as firing rate and filtering capabilities. In the experiments presented in this thesis, I studied modifications mediated by serotonin in the response properties of neurons that receive direct sensory inputs from peripheral sensors in the weakly electric fish. These neurons also receive a rich serotonergic innervation from the raphe nuclei. In a first set of studies, in an in vitro preparation I found that the effect of

Abstract:

The electrosensory lateral line lobe (ELL) is the first order electrosensory processing station in the brain of the electric fish Apteronotus leptorhynchus, and is the only nucleus to receive input from electroreceptors on the skin. The ELL is subdivided into three maps: the centromedial segment (CMS), centrolateral segment (CLS), and lateral segment (LS) which receive input from tuberous electroreceptors processing high frequency signals. Two feedback pathways from higher order nuclei, the nucleus praemenintialis (nP) and the eminentia posterior granularis (EGp) are integral to processing in

Abstract:

Accurate sensory processing of the environment is a critical function for any organism to survive. In order to accomplish this function neurons must be specifically tuned to respond optimally to relevant stimuli in their environment. One effective way of efficiently encoding information is for neurons to adapt their responses to stimuli arising from different behavioral contexts. Neuromodulators such as serotonin (5-HT) are thought to help mediate such adaptations. The 5-HT system has been well conserved through evolution across vertebrates, suggesting that its function also been conserved

Abstract:

A classe Chondrichthyes é representada por animais de esqueleto cartilaginoso e calcificação prismática. Eles são divididos em duas subclasses, Elasmobranchii (tubarões e raias) e Holocephali (quimeras), que têm uma história evolutiva de mais de 400 milhões de anos. Devido à grande adaptabilidade destes animais em diferentes habitats, eles desenvolveram sofisticadas habilidades sensoriais, como os sistemas mecanorreceptor da linha lateral e eletrossensorial. A maior ordem de tubarões, a Carcharhiniformes tem a maioria dos representantes ocorrendo no Brasil. Entre eles, destacamos o tubarão-azu

Abstract:

A stochastic leaky integrate-and-fire neuron model was implemented in this study to simulate the spiking activity of the electrosensory "P-unit" receptor neurons of the weakly electric fish Apteronotus leptorhynchus. In the context of sensory coding, these cells have been previously shown to respond in experiment to natural random narrowband signals with either a linear or nonlinear coding scheme, depending on the intrinsic firing rate of the cell in the absence of external stimulation. It was hypothesised in this study that this duality is due to the relation of the stimulus to the neuron's e
