Dissociation Between Conscious And Unconscious Processes As A Criterion For Sentience, Ivan Ivanchei, Nicolas Coucke, Axel Cleeremans
Dissociation Between Conscious And Unconscious Processes As A Criterion For Sentience, Ivan Ivanchei, Nicolas Coucke, Axel Cleeremans
Animal Sentience
Based on the literature on human consciousness, we suggest that to demonstrate sentience in a system, one needs to demonstrate both conscious and unconscious processing in the system. Major theories of consciousness require the existence of both conscious and unconscious processes. Contrasting effects of conscious and unconscious processes have been successfully used in human studies and have begun being applied in animal sentience research as well.

Animal Sentience
Segundo-Ortin’s (2023) target article invites us to consider the possibility that plants can experience subjectively felt states. We discuss this speculation on the basis of the functional neurobiology of consciousness. We suggest that demonstrating plant sentience would require that we identify not only behaviors analogous to those exhibited by sentient creatures, but also the functional analogues of the mechanisms causing such behaviors. The lack of clear evidence for any kind of integration between self-states, self-movement, environmental states, memory, or affective communication within plants suggests that plant sentience remains an admittedly fascinating, but ultimately merely provocative speculation.

Sensing Is A Far Cry From Sentience, Antonio Damasio, Hanna Damasio
Animal Sentience
The hypothesis that plants might be sentient confuses the notion of sentience (or consciousness) with that of sensing. Sentience/consciousness implies feeling, experience, and subjectivity. Sensing does not. Plants can sense/detect and even respond appropriately in the absence of any sentience/consciousness.
Plants Lack The Functional Neurotransmitters And Signaling Pathways Required For Sentience In Animals, David G. Robinson, Michael R. Blatt, Andreas Draguhn, Lincoln Taiz, Jon Mallatt

Animal Sentience
We cannot agree with Segundo-Ortin and Calvo that plants are sentient organisms. We have critically examined several aspects of their target article, and find their claims are not supported by the published evidence. We address these claims in sections on whether plants have a ‘neurobiology’ analogous to that of animal nervous systems, including neurotransmitters and synaptic receptors that respond to anesthetics; and whether plant signaling resembles neural transmission. For the latter, we especially consider the unique way plants signal their responses to wounding. Although the plant vascular system has been compared to the animal nervous system, animal blood vessels would …
Consciousness, Evolution, And The Self-Organizing Brain, Karen Seymour
Consciousness, Evolution, And The Self-Organizing Brain, Karen Seymour
Journal of Conscious Evolution
While evolution is guided by natural selection, it is internally driven by self-organizing processes. The brain encompasses these complementary forces and dynamics of evolution in both its structure and dynamics by embodying a historical record of the factors that have shaped it throughout its evolutionary past, as well as by being shaped by selective parameters in real time. Self-organization is evident in not only the brain’s structure and form, but also in the processes that support consciousness. From the convergence of complex structure and the novelty-generating dynamics of chaos that both characterize the brain arises the experience of explicit consciousness, …
