Environmental enrichment attenuates cue-induced reinstatement of sucrose seeking in rats

Abstract: This study examined the effect of environmental enrichment on sucrose seeking in rats made abstinent from sucrose for 1 month, as measured by response for a tone + light cue previously associated with 10% sucrose self-administration. Rats were either enriched throughout the study (experiment 1) or only after sucrose self-administration training (experiment 2). Enrichment consisted of either housing the rats in pairs or grouping four rats (ENR4) in a large environment, both with novel objects. Controls (CON) we… Show more

“…While many of the characteristic of sucrose consumption are like ethanol consumption, very little research has been directed toward investigating the role of social and environmental factors in sucrose consumption (see Table 2). With the exception of one study (Grimm et al, 2008) focusing on relapse behavior rather than the development and maintenance of sucrose consumption; the currently available research suggests neither social nor environmental nor a combination of these factors influence sucrose consumption (Brenes & Fornaguera, 2008;Hall, Humby, Wilkinson, & Robbins, 1997;Moles & Cooper, 1995). It remains, however, undetermined whether moving rats from deprived environments to enriched environments and vice versa impacts subsequent sucrose consumption, similar to ethanol consumption.…”

“…Environmental enrichment has been shown to decrease the activating effects of psychostimulants [46,47] or reduce self-administration of psychostimulants [48,49] as well as natural rewards, such as sucrose [50]. Regarding behavioral sensitization to nicotine, environmental enrichment failed to alter sensitization to nicotine in NQ-treated rats, which were equivalent to isolated NQ rats also sensitized to nicotine.…”

“…Utilizando modelos animales, se han realizado diferentes intentos para evaluar cómo las manipulaciones experimentales del ambiente postnatal pueden utilizarse para "tratar" los efectos de la exposición fetal al alcohol. Estas aproximaciones incluyen el "handling" (manoseo) postnatal, el EE y el entrenamiento basado en la rehabilitación motora (veáse revisión de Aunque todavía no se comprenden bien los cambios moleculares que subyacen a los efectos del EE sobre la adicción (Burrows, McOmish, y Hannan, 2010; Stairs y Bardo, 2009), se sugiere que la exposición a este ambiente podría proporcionar a los sujetos mayor capacidad de discriminar la presencia de recompensa (Grimm et al, 2008). En estudios previos, las ratas enriquecidas muestran un incremento en el condicionamiento tanto de la preferencia como de la aversión a un lugar (Bardo et al, 1995;Smith et al, 2005;Smith, Bryant, y McClean, 2003), así como extinción acelerada del condicionamiento del miedo (Pietropaolo, Feldon, Alleva, Cirulli, y Yee, 2006).…”

“…Ello indicaría que los animales criados en ambientes enriquecidos muestran mayor capacidad de aprendizaje acerca del significado de los estímulos asociados a la recompensa y el castigo, y de distinguir entre "disponibilidad" y "no disponibilidad" del refuerzo. Durante el proceso de extinción, también parecen aprender más rápidamente que sus acciones no van a ser recompensadas y, por ello, dejan de responder más pronto que los criadas en ambientes empobrecidos (Grimm et al, 2008), aunque la exposición al EE parece disminuir sus impulsividad (Hellemans, Nobrega, y Olmstead, 2005;Perry, Stairs, y Bardo, 2008). Estos cambios podrían ir asociados a una disminución de la vulnerabilidad a las conductas de recaída (Grimm et al, 2008).…”
