2. 6. Active Memory Processing on Multiple Time-scales in Simulated Cortical Networks with Hebbian Plasticity

   Author : Florian Fiebig; Anders Lansner; Tim Vogels; KTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Working memory; Long-term memory; consolidation; spiking; neural network; BCPNN; cortical microcircuit; Tillämpad matematik och beräkningsmatematik; Applied and Computational Mathematics; Biological Physics; Biologisk fysik;

   Abstract : This thesis examines declarative memory function, and its underlying neural activity and mechanisms in simulated cortical networks. The included simulation models utilize and synthesize proposed universal computational principles of the brain, such as the modularity of cortical circuit organization, attractor network theory, and Hebbian synaptic plasticity, along with selected biophysical detail from the involved brain areas to implement functional models of known cortical memory systems.

5. 8. Designing Electricity Distribution Network Charges for an Efficient Integration of Distributed Energy Resources and Customer Response

   Author : Ibtihal Abdelmotteleb; Tómas Gómez; Javier Reneses; Rafael Cossent Árin; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; customer response; distributed energy resources; distribution network charges; local flexibility mechanisms; Electrical Engineering; Elektro- och systemteknik;

   Abstract : A significant transformation has been gradually taking place within the energy sector, mainly as a result of energy policies targeting environmental objectives. Consequently, the penetration of Distributed Energy Resources (DERs) has been escalating, including self-generation, demand side management, storage, and electrical vehicles. READ MORE

6. 9. Modeling Biochemical Network Involved in Striatal Dopamine Signaling

   Author : Anu G. Nair; Jeanette Hellgren Kotaleski; Omar Gutierrez Arenas; Upinder Singh Bhalla; Jakob Kisbye Dreyer; KTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Dopamine signaling; Striatum; Reward learning; Acetylcholine; Mass-action modeling; FRET biosensor; Adenosine; Eligibility trace; Computer Science; Datalogi;

   Abstract : In this thesis, I studied the molecular integration of reward-learning related neuromodulatory inputs by striatal medium-sized projection neurons (MSNs) using mass-action kinetic modeling.It is known that, in reward learning, an unexpected reward results in transient elevation in dopamine (peak) whereas omission of an expected reward leads to transient dopamine decrease (dip).
