摘要:

在计算神经科学中,准确预测视觉皮层对自然视觉刺激的神经反应仍然是一个挑战。在这项工作中,我们引入了V1T,一种新颖的基于视觉Transformer的架构,它跨动物学习共享的视觉和行为表征。我们在两个从小鼠初级视觉皮层记录的大型数据集上评估了我们的模型,并在预测性能上比之前的基于卷积的模型提高了超过12.7%。此外,我们展示了Transformer学习到的自注意力权重与群体感受野相关。因此,我们的模型为神经反应预测设定了新的基准,并且可以与行为和神经记录联合使用,以揭示视觉皮层有意义的特征。

英文摘要:

Accurate predictive models of the visual cortex neural response to natural visual stimuli remain a challenge in computational neuroscience. In this work, we introduce V1T, a novel Vision Transformer based architecture that learns a shared visual and behavioral representation across animals. We evaluate our model on two large datasets recorded from mouse primary visual cortex and outperform previous convolution-based models by more than 12.7% in prediction performance. Moreover, we show that the self-attention weights learned by the Transformer correlate with the population receptive fields. Our model thus sets a new benchmark for neural response prediction and can be used jointly with behavioral and neural recordings to reveal meaningful characteristic features of the visual cortex.
