Brain Inhibitory Mechanisms Are Involved in the Processing of Sentential Negation, Regardless of Its Content. Evidence From EEG Theta and Beta Rhythms

David Beltrán, Yurena Morera, Enrique García-Marco, Manuel de Vega
2019 Frontiers in Psychology  
The two-step process account of negation understanding posits an initial representation of the negated events, followed by a representation of the actual state of events.  ...  In the current EEG study, we ponder whether the reusing of response inhibition processes by negation is constrained to action-related contents or consists of a more general-purpose mechanism.  ...  Neural Inhibition in Negated Action Sentences Recently, it has been proposed that one of the neural mechanisms underlying the processing of negation is the response inhibition network of the brain (de  ...

On the Embodiment of Negation in Italian Sign Language: An Approach Based on Multiple Representation Theories

Valentina Cuccio, Giulia Di Stasio, Sabina Fontana
2022 Frontiers in Psychology  
Inspired by an approach to the embodiment of concepts known as Multiple Representation Theories (MRT, henceforth), the present paper explores negation as an embodied action that relies on both sensorimotor  ...  In the present research we will apply the MRT framework for exploring negation in Italian sign language (LIS).  ...  Since the modality of acquisition impacts on the different representation of abstract and concrete concepts/meanings in the brain, it might be extremely useful to have a look at psycholinguistic data on  ...

A brain-liver circuit regulates glucose homeostasis

Alessandro Pocai, Silvana Obici, Gary J. Schwartz, Luciano Rossetti
2005 Cell Metabolism  
Increased glucose production (GP) is the major determinant of fasting hyperglycemia in diabetes mellitus.  ...  Thus, hypothalamic lipid sensing potently modulates glucose metabolism via neural circuitry that requires the activation of K ATP and selective brainstem neurons and intact vagal input to the liver.  ...  Thus, this brain-liver circuit ap-related to its inhibitory action on feeding behavior.  ...

Pain: A Distributed Brain Information Network?

Hiroaki Mano, Ben Seymour
2015 PLoS Biology  
In support of this view, Woo and colleagues present evidence that distinct brain networks support the subjective changes in pain that result from nociceptive input and self-directed cognitive modulation  ...  However, since Penfield's failure to convincingly locate a "pain cortex" during his classic awake brain stimulation studies in the 1950s [1], trying to piece together the pain system in the brain has been  ...  higher in the brain [3, 4] .  ...

How the brain responds to the destruction of money

Cristina Becchio, Joshua Skewes, Torben E. Lund, Uta Frith, Chris Frith, Andreas Roepstorff
2011 Journal of Neuroscience Psychology and Economics  
Is our attitude to money like that to any other tool even though its use is symbolic and is not implemented in its physical structure?  ...  Moreover, this activation is the greater the higher the value of the banknote.  ...  That fusiform activity was modulated by the value of the money presented supports this interpretation, and suggests that the categorical representations in this region are fine-grained enough to distinguish  ...

Neuropeptide Transmission in Brain Circuits

Anthony N. van den Pol
2012 Neuron  
Neuropeptides are found in many mammalian CNS neurons where they play key roles in modulating neuronal activity.  ...  Other peptides such as neuropeptide Y (NPY) are synthesized throughout the brain, and neurons that synthesize the peptide in one region have no anatomical or functional connection with NPY neurons in other  ...  Any specific role of the peptide relevant to the releasing neuron would be negated if the same peptide from other brain regions was diffusing long distances.  ...
