Max Tegmark is directly linked to the brain through his scientific research and publications, specifically his calculations on decoherence rates {fact:2, fact:3, fact:4} and his influential arguments that the brain functions as a classical system rather than a quantum computer {fact:1, fact:5, fact:6, fact:7}.

measurementA revised version of Max Tegmark's model of quantum decoherence in the brain provides decoherence times of 10 to 100 microseconds, which proponents of the Penrose-Hameroff model argue can be extended to the neurophysiologically relevant range of 10 to 100 milliseconds under specific assumptions.
claimMax Tegmark (2000) criticized the possibility that quantum states can survive long enough in the thermal environment of the brain to be relevant for consciousness.
measurementMax Tegmark estimates the decoherence time of tubulin superpositions due to interactions in the brain to be less than 10^-12 seconds.

claimMax Tegmark argues that the brain is likely not a quantum computer in his 2000 paper 'Why the brain is probably not a quantum computer' published in Information Sciences.
measurementMax Tegmark calculated the decoherence rates of neurons and concluded that the brain is a classical rather than a quantum system, and that quantum mechanics does not relate to consciousness in any fundamental way.
Non-physicalist Theories of Consciousness cambridge.org 1 fact
claimMax Tegmark argued in 2000 that the brain is too 'warm, wet and noisy' to maintain quantum coherence for meaningful amounts of time.

perspectiveThe authors of 'Quantum Theory of Consciousness' disagree with Max Tegmark's proposal that the brain is a classical system because they believe it ignores the order, correlation, and coherence that dominate the brain and life.
