[HTML][HTML] Coincidence of cholinergic pauses, dopaminergic activation and depolarisation of spiny projection neurons drives synaptic plasticity in the striatum

JNJ Reynolds, R Avvisati, PD Dodson… - Nature …, 2022 - nature.com
Dopamine-dependent long-term plasticity is believed to be a cellular mechanism underlying
reinforcement learning. In response to reward and reward-predicting cues, phasic …

Hydroxyapatite/gelatin/gellan sponges as nanocomposite scaffolds for bone reconstruction

…, GD Guerra, C Cristallini, P Urciuoli, R Avvisati… - Journal of Materials …, 2012 - Springer
The aim of this work was the morphological, physicochemical, mechanical and biological
characterization of a new composite system, based on gelatin, gellan and hydroxyapatite, and …

Distinct modulation of the endocannabinoid system upon kainic acid-induced in vivo seizures and in vitro epileptiform bursting

F Fezza, MC Marrone, R Avvisati… - Molecular and Cellular …, 2014 - Elsevier
There is clear evidence on the neuroprotective role of the endocannabinoid (eCB) signaling
cascade in various models of epilepsy. In particular, increased levels of eCBs protect …

[HTML][HTML] Ultrasonic vocalization in rats self-administering heroin and cocaine in different settings: evidence of substance-specific interactions between drug and setting

R Avvisati, L Contu, E Stendardo, C Michetti… - …, 2016 - Springer
Rationale Clinical and preclinical evidence indicates that the setting of drug use affects drug
reward in a substance-specific manner. Heroin and cocaine co-abusers, for example, …

Distributional coding of associative learning within projection-defined populations of midbrain dopamine neurons

R Avvisati, AK Kaufmann, CJ Young, GE Portlock… - bioRxiv, 2022 - biorxiv.org
Midbrain dopamine neurons are thought to play key roles in learning by conveying the difference
between expected and actual outcomes. While this teaching signal is often considered …

Intravenous self‐administration of benzydamine, a non‐steroidal anti‐inflammatory drug with a central cannabinoidergic mechanism of action

R Avvisati, M Meringolo, E Stendardo… - Addiction …, 2018 - Wiley Online Library
Benzydamine (BZY) is a non‐steroidal anti‐inflammatory drug used for the topical treatment
of inflammations of the oral and vaginal mucosae. Virtually nothing is known about the …

Distinct populations of neurons activated by heroin and cocaine in the striatum as assessed by catFISH

P Vassilev, R Avvisati, E Koya, A Badiani - eneuro, 2020 - eneuro.org
Despite the still prevailing notion of a shared substrate of action for all addictive drugs, there
is evidence suggesting that opioid and psychostimulant drugs differ substantially in terms of …

The active heroin metabolite 6-acetylmorphine has robust reinforcing effects as assessed by self-administration in the rat

R Avvisati, IL Bogen, JM Andersen, V Vindenes… - …, 2019 - Elsevier
Previous studies have suggested that at least some of the behavioral effects of heroin might
be mediated by its active metabolite 6-acetylmorphine (6-AM). The aim of the present study …

C. 7-SUBSTANCE-SPECIFIC INFLUENCES OF SETTING ON DRUG REWARD: AN ULTRASONIC VOCALIZATION STUDY IN RATS SELF-ADMINISTERING HEROIN …
