arXiv, 2016 We consider the application of approximate Bayesian Computation (ABC) in the context of medical imaging data. We consider the parameter estimation of compartmental models in PET imaging analysis, and provide a simple ABC algorithm for its estimation. We demonstrate the utility of the proposed estimation methods on a neurotransmitter response model, and

Biophysics of risk aversion based on neurotransmitter receptor theory [PDF]
Neuro Endocrinol Lett. 2008 Aug;29(4):399-404.
http://node.nel.edu/?node_id=7744, 2011 Decision under risk and uncertainty has been attracting attention in neuroeconomics and neuroendocrinology of decision-making. This paper demonstrated that the neurotransmitter receptor theory-based value (utility) function can account for human and animal risk-taking behavior.

A Neuransistor with Excitatory and Inhibitory Neuronal Behaviors for Liquid State Machine
Advanced Materials, EarlyView.The neuransistor integrates hybrid excitatory and inhibitory dynamics, enabling liquid state machine implementation. It operates via charge trapping in a two‐dimensional electron electron gas (2DEG)/TiO2−x structure and features a three‐terminal design for efficient masking functionality. Simulations demonstrate its effectiveness in predicting temporal

Computational modeling of neuronal networks [PDF]
arXiv, 2012 Human brain contains about 10 billion neurons, each of which has about 10~10,000 nerve endings from which neurotransmitters are released in response to incoming spikes, and the released neurotransmitters then bind to receptors located in the postsynaptic neurons.
