Visual image reconstruction from brain activity via latent representation www.annualreviews.org/content/jour... by @ykamit.bsky.social et al.; mental imagery, #neuroscience
Psychological measurement of subjective visual experiences through image reconstruction. (a) Mapping of brain, stimulus, and mind. Dots represent instances of visual experience (e.g., an image, perception, and corresponding brain activity). Veridical perception assumes that the mind accurately represents stimuli. The brain–mind mapping is considered fixed, while the brain–stimulus relationship is empirically identified. (b) Nonveridical perception (e.g., mental imagery, attentional modulation, and illusions) occurs when perceived content diverges from physical properties. The fixed brain–mind mapping and decoders trained on brain activity under veridical conditions allow the reconstruction of mental content as an image. (c) Reconstruction of mental imagery is achieved using models trained on brain activity from natural images.

🧵 time! 1/15 Why are CNNs so good at predicting neural responses in the primate visual system? Is it their design (architecture) or learning (training)? And does this change along the visual hierarchy? 🧠🤖 🧠📈

NeuroTorch: A Python library for neuroscience-oriented machine learning
Machine learning (ML) has become a powerful tool for data analysis, leading to significant advances in neuroscience research. While ML algorithms are proficient in general-purpose tasks, their highly technical nature often hinders their compatibility with the observed biological principles and constraints in the brain, thereby limiting their suitability for neuroscience applications. In this work, we introduce NeuroTorch, a comprehensive ML pipeline specifically designed to assist neuroscientists in leveraging ML techniques using biologically inspired neural network models. NeuroTorch enables the training of recurrent neural networks equipped with either spiking or firing-rate dynamics, incorporating additional biological constraints such as Dale's law and synaptic excitatory-inhibitory balance. The pipeline offers various learning methods, including backpropagation through time and eligibility trace forward propagation, aiming to allow neuroscientists to effectively employ ML approaches. To evaluate the performance of NeuroTorch, we conducted experiments on well-established public datasets for classification tasks, namely MNIST, Fashion-MNIST, and Heidelberg. Notably, NeuroTorch achieved accuracies that replicated the results obtained using the Norse and SpyTorch packages. Additionally, we tested NeuroTorch on real neuronal activity data obtained through volumetric calcium imaging in larval zebrafish. On training sets representing 9.3 minutes of activity under darkflash stimuli from 522 neurons, the mean proportion of variance explained for the spiking and firing-rate neural network models, subject to Dale's law, exceeded 0.97 and 0.96, respectively. Our analysis of networks trained on these datasets indicates that both Dale's law and spiking dynamics have a beneficial impact on the resilience of network models when subjected to connection ablations. NeuroTorch provides an accessible and well-performing tool for neuroscientists, granting them access to state-of-the-art ML models used in the field without requiring in-depth expertise in computer science. ### Competing Interest Statement The authors have declared no competing interest.

💯 Hallucination is totally the wrong word, implying it is perceiving the world incorrectly. But it's generating false, plausible sounding statements. Confabulation is literally the perfect word. So, let's all please start referring to any junk that an LLM makes up as "confabulations".
