Oct 22, 2021 · The pronounced O 2 dependency of neuronal activity prompted us to explore an innovative concept of photosynthetic O2 replenishment of the brain. Following transcardial injection of green algae or cyanobacteria and their vascular distribution in Xenopus tadpoles, illumination of the brain triggered a robust and constant production of oxygen.

Jul 3, 2019 · In claiming that plants have consciousness, ‘plant neurobiologists’ have consistently glossed over the remarkable degree of structural and functional complexity that the brain had to evolve for consciousness to emerge. Here, we outline a new hypothesis proposed by Feinberg and Mallat for the evolution of consciousness in animals. Based on a survey of the brain anatomy, functional ...

The study of plant cognition stems from the idea that plants are able to learn and adapt to their environment with only a stimulus, integration, and response system. While proven that plants do indeed lack a brain and the function of a conscious working nervous system, plants are still somehow capable of adapting to their environment and ...
Jan 3, 2020 · The critics, who espoused the idea that cognition begins and ends in the brain, were concerned by the fact that it seemed particularly difficult to empirically test and demonstrate that a given process is an inextricable part of the observed cognitive system. 24 – 28 Kaplan 29 proposed to resolve the issue by using the mutual manipulability criterion. 30, 31 According to this criterion, if ...

Aug 1, 2019 · Neurobiology refers to the biology of the nervous system, and plants manifestly lack nervous systems. This particular lexical complaint was soon resolved when the group quietly changed its name a few years later from the Society for Plant Neurobiology to the more acceptable Society for Plant Signaling and Behavior.

Jan 3, 2020 · Citation 3 And with no brain at all, plants too exhibit a wide range of exquisite behaviors, Citation 4 which has recently revealed unsuspected cognitive capacities in these non-neural organisms (e.g. Gagliano et al. Citation 5, Citation 6). The new experimental evidence casts doubts on the validity of the classical view of cognition centered on the brain, and instead, more closely aligns with ...

Sep 23, 2021 · Hence, the behavioral evidence thus suggests that plants could qualify to be sentient organisms. A second argument concerns the lack of a nervous system in plants. If having a nervous system is a pre-requisite for being conscious, then plants are automatically excluded. The reason why this second argument is debatable is two-fold.
