Discussion of the paper "How deep is the brain? The shallow brain hypothesis" Suzuki, Cyiriel, and Aru. Presentation by Jaan Aru followed by discussion.
00:04 Jaan Aru presents the shallow brain hypothesis in the neuroscience and philosophy salon. 02:49 Most neuroscientists focus on the cortex and disregard the importance of subcortical structures like the Thalamus. 08:33 The shallow brain hypothesis challenges the dominant idea of cortical hierarchical processing. 11:28 Each cortical area sends output to subcortical structures 16:55 The brain has a hierarchical structure with modules and loops that can affect behavior at an early processing stage. 19:17 Modular architecture and updating less synapses is important in the brain. 24:17 The shallow brain hypothesis suggests that subcortical areas like the basal ganglia help with combining higher-order thinking and cognition. 26:43 The shallow brain hypothesis suggests that architectures with output from each cortical area could outperform deep architectures in tasks requiring compositionality and flexible combination. 31:48 Subcortical areas may have a cleaner and more primitive processing compared to the cortex. 33:55 The hypothesis suggests that the prefrontal cortex is a special place where everything comes together. 38:22 Loop theory supports working memory and attention 40:41 The shallow brain hypothesis suggests that the depth of the brain doesn't matter based on anatomical facts. 45:36 The amygdala plays a unique role in the shallow brain hypothesis. 47:49 The brain is better understood as 100,000 cortical agents trying to affect the subcortex. 52:27 The brain is not shallow, as it has complex hierarchical models and compositionality built on top. 54:31 The brain has shallow anatomical connections and deep architectures in Deep learning. 58:59 The human brain has a significantly higher number of cortical columns compared to animals. 1:01:17 Layer 5 PT cells project to the thalamus, modulating thalamic processing and driving higher order thalamic structures. 1:06:12 The brain has different processing modes and subcortical connections can handle novel stimuli. 1:08:48 Thalamus plays a crucial role in brain processes and is more intriguing than the LGN. 1:13:31 The speaker wraps up the discussion and thanks everyone for participating.
