In order to enable an iCal export link, your account needs to have an API key created. This key enables other applications to access data from within Indico even when you are neither using nor logged into the Indico system yourself with the link provided. Once created, you can manage your key at any time by going to 'My Profile' and looking under the tab entitled 'HTTP API'. Further information about HTTP API keys can be found in the Indico documentation.
Additionally to having an API key associated with your account, exporting private event information requires the usage of a persistent signature. This enables API URLs which do not expire after a few minutes so while the setting is active, anyone in possession of the link provided can access the information. Due to this, it is extremely important that you keep these links private and for your use only. If you think someone else may have acquired access to a link using this key in the future, you must immediately create a new key pair on the 'My Profile' page under the 'HTTP API' and update the iCalendar links afterwards.

Smooth-pursuit learning in a closed-loop cortex - basal-ganglia model with spiking neurons
Pursuit eye movements require an active feedback loop between stimulus perception and the selection of the appropriate eye motor command to track a moving stimulus. The question how the action selection takes place and more specifically how the circuitry involved in pursuit eye movements develops is not resolved.
In this seminar, a multi-layer spiking neural network model for the development of pursuit eye movements is presented. Our main hypothesis is that the Basal Ganglia (BG) are crucial for the development of eye movements and that this learning process can be described as a form of habit formation.
The model operates in a closed-loop between sensory perception and action-selection and is based on a model of the BG which enables the system to learn and adapt to changes in the environment. A sensory layer inspired by retinotopic cortical areas forwards information about stimulus speed, direction and position to the BG which in turn selects a motor command initiating an eye movement which dynamically changes the perceived retinal stimulus. I will present results using a supervised learning paradigm and discuss future directions including unsupervised development of the pursuit pathway and the role of delays in this closed-loop system.
