A road map to the beauty of the brain 2 – how behavioural architecture emerges from cortical developmental principles

Che bella cosa na jurnata ’e sole ! ;-) After having some delicious meringues during the coffee break, we started off as Rodney reminded us of some important numbers re. cortical circuits. Lay design of canonical circuit to emergence of behaviour – a cortical sheet for computation Rodney first laid out the basic design of the canonical cortical circuit – there are about 10-100K neurons and 3.2 X 10^8 synapses per mm^3 in the Human brain. Cortex is extremely (axon rich and) synapse-dense (where excitatory synapses are formed onto the spine head of excitatory pyramidal neurons, whereas inhibitory synapses are formed on the dendritic shaft). As illustrated in the cartoon, feedforward thalamic drive (only 1%) excites spiny stellate cells in L4 that provides excitation to L2/3 pyramidal neurons (via first intra-cortical L4-L2/3 synapse). There are few interconnections between spiny stellate neurons (15%) compared to in L2/3 (30-40% recurrent connectivity). L2/3 co

A road map to the beauty of the brain – how to build a brain -- Rodney Douglas, ETH-Zürich

Giacomo inaugurated the 2018 CapoCaccia meeting by saying a few words about the organisation of the workshop and introducing us to the key contributors who helped organise the meeting this year - Moritz Milde and Gaby Michel, and others like Elisa Donati and Nicoletta Risi. The first lecture ' A road map to the beauty of the brain' was delivered by Rodney Douglas. Rodney began his lecture by reminding us of a 3000-year old problem – how the ‘silent’ single cell (in the form of an ‘egg’) turns into a functional chicken, i.e., how the blank slate (tabula rasa) of developing cortical circuits accommodates emergence of functional specialisation contributing to animal behaviour! Rodney began by describing how in developing vertebrates, embryonic precursors form neural tube (progenitor of CNS – brain and the spinal cord). Along the antero-posterior axis (2D-grid), fore-, mid- and hind-brain structures are laid together with spinal cord by morphogenic gradients

Movement and action (zebrafish and suffering, movement control by midbrain and cortex)

Rained very hard last night, continuing today. New people: Andrew Rowley from Manchester ("Helping to use SpiNNaker effectively). Julia Buhmann, connectomics, DNNs, ("Do not eat meat"). Florian Engert, neuroscience, larval zebrafish ("For sale: fish feelings lovingly explained"). For Friday, 2h wrapup, followed by demo sessions. Florian Engert started off talking about fish feelings, technically valence, claiming that audience would think this more interesting than mechanisms or networks. He took larval zebrafish as example, which they study. There are 100k neurons in this vertebrate brain. They have mammalian behaviors. They are translucent so they can measure all neurons. Then somehow a discussion of suffering started. By definition alpha fibers are stimulated. But these still need a brain to turn pain to what is defined as suffering. It is pain input as represented in the brain, not peripheral nervous system. He then drew a scale, "Ba
