Fig. 3: Validation of region-based feature coding using Microsoft COCO stimuli.
From: A neuronal code for object representation and memory in the human amygdala and hippocampus
a An example neuron demonstrating region-based feature coding. b The aggregated tuning regions of the neuronal population. Legend conventions as in Fig. 1. c An example COCO feature neuron showing elevated responses for ImageNet stimuli falling in its tuning region. The feature space was constructed for combined ImageNet and COCO stimuli. The size of the dot indicates the firing rate. The red outline delineates the tuning region of the neuron (identified by the COCO stimuli). Black: objects from the COCO stimuli. Gray: objects from the ImageNet stimuli. Magenta: ImageNet stimuli falling in the tuning region of the COCO feature neuron. d Population results comparing neuronal response to ImageNet stimuli falling in vs. out of the tuning region (n = 22). Each dot represents a neuron. Error bars denote ±SEM across neurons. Asterisks indicate a significant difference between the In vs. Out responses using a right-tailed paired t-test (P < 0.05). The example neuron shown in (c) is highlighted in a darker color. Source data are provided as a Source Data file.
