emotion

n. a complex reaction pattern, involving experiential, behavioral, and physiological elements, by which an individual attempts to deal with a personally significant matter or event. The specific quality of the emotion (e.g., fear, shame) is determined by the specific significance of the event. For example, if the significance involves threat, fear is likely to be generated; if the significance involves disapproval from another, shame is likely to be generated. Emotion typically involves feeling but differs from feeling in having an overt or implicit engagement with the world. —emotional adj.

transfer function model

1. a model used in functional magnetic resonance imaging to describe the shape of responses. A neuron receives a number of inputs, each of which comes via a connection that has a strength or weight; these weights correspond to the synaptic efficacy of the neuron. Each neuron also has a single threshold value. Activation of the neuron is determined by the weighted sum of the inputs minus the threshold. The activation signal is passed through a transfer function to produce the output of the neuron.

2. in time-series analysis, a type of model used to forecast a time series that is influenced by present and past values of other time series.
