How are inputs made into motion? We analyze feedback systems in auditory systems in birds. Motivation Birds are very good at producing and reproducing songs by moving their vocal cords complexly (sensory motor learning). We want to learn how they learn and then extrapolate on human or other kinds of speech learning. Birds and Humans do not have much of a common ancestry (last one was fishes). 71% of the birds, both female and male birds sing, for Zebra finch it is a mating behaviour, so only male sing. ...

Humans are not rational. See (Dostoevsky 1864), the parable of the destroying free will. In this note we will describe some behavioural economics ideas that could be interesting in this side. We will see dopamine response will be very important in this context, and see how we can interpret it as an utility. Economical Games The rules of the Ultimatum game The proposer makes an offer as to how this money should be split between the two. The second player (the risponder) can either accept or reject this offer. If it is accepted, the money is split as proposed, but if the risponder rejects the offer, then neither player receives anything. ...

Associative Conditioning Classical Conditioning First started with associative conditioning, which means cue -> reward signal and similars. Pavlov’s experiment Pavlov was interested in digestive systems of dogs, and discovered this by chance. Then he notices that if we show food to dog, they start to salivate (response to food stimulus). If paired with sound (tuning fork) they start to salivate even if they just hear the sound. He defines two states: ...

Metodi di registrazione informazione Ci stiamo chiedendo in che modo possiamo registrare attività del cervello e quindi cercare di fare decoding delle informazioni presenti Prima parliamo di alcune tecniche non invasive che ci permettono di vedere alcune attività presenti nel cervello. Metodi macroscopici Functional Magnetic Resonance Imaging Un metodo è fMRI. (ci sono cose ) TODO capire come funziona Electro-Encephalo-Gram EEG che prende direttamente dai segnali Ma il drawback di entrambi è che non registrano attività del singolo array. ...
