Transcranial direct current stimulation over the right DLPFC selectively modulates subprocesses in working memory
2018
Background Working memory, as a complex system, consists of two independent components: manipulation and maintenance process, which are defined as executive control and storage process. Previous studies mainly focused on the overall effect of transcranial direct current stimulation (tDCS) on working memory. However, little has been known about the segregative effects of tDCS on the sub-processes within working memory. Method Transcranial direct current stimulation, as one of the non-invasive brain stimulation techniques, is being widely used to modulate the cortical activation of local brain areas. This study modified a spatial n-back experiment with anodal and cathodal tDCS exertion on th…
Anosognosia and Metacognition in Alzheimer’s Disease
2015
While metacognition and anosognosia have long been studied as distinct concepts, more recently we have endeavored to construct a theoretical framework for exploring how metacognition can contribute to our understanding of anosognosia and vice versa. Following this approach, with a particular focus on Alzheimer’s disease (AD), this chapter first gives an overview of the key experimental findings and issues on metacognition in AD patients: in particular, overconfidence and absolute awareness; the sensitivity approach; the fractionation of metacognition in AD; the neural substrates of metacognition in the Alzheimer brain; and metacognitive control in these patients. Second, the chapter discuss…
Amnesia and the hippocampus
2006
PURPOSE OF REVIEW: Long-term memory impairments have great medical significance and a considerable health and economic burden. Understanding their cognitive and neuroanatomical underpinnings is of crucial importance. Severe amnesia is usually observed following bilateral hippocampal pathology. This review addresses the precise role of the hippocampus and related medial temporal lobe structures in amnesia. RECENT FINDINGS: Disagreements exist over whether, following selective hippocampal damage: retrograde amnesia for episodic memories is temporally limited or extensive and ungraded; anterograde amnesia involves both recollective and familiarity processes. It is accepted that material specif…
"L'albero Falcone" e i suoi epigoni. La propagazione vegetale della memoria antimafia
2021
Le stragi di Capaci e via D’Amelio segnano un punto di svolta nel linguaggio con cui i movimenti antimafia costruiscono la memoria pubblica della violenza mafiosa. Uno dei tratti salienti di questa svolta è la proliferazione di luoghi di memoria che ruotano intorno a figure arboree. Il capostipite di questa genealogia è l’albero Falcone, noto come punto di raccolta per le manifestazioni del 23 maggio, la giornata della legalità. Nel corso degli anni ’90, il modello memoriale costruito intorno all’albero si sviluppa e si diffonde, mentre sono sempre già frequenti le piantumazioni di alberi in memoria delle vittime della mafia. L’articolo cerca di esplicitare le forme semiotiche soggiacenti a…
Tradizione socialista e martirologio antimafia. La memoria di Lorenzo Panepinto e Bernardino Verro
2023
Socialist victims of the Mafia, Bernardino Verro and Lorenzo Panepinto were killed in the 1910s (1911 and 1915). For a long time, they were commemorated by the Socialist Party, which celebrated them as victims of the class struggle. However, as Marxist identities weakened in the 20th century, their memory was increasingly discussed as part of a debate on mafia victims. The essay aims to study this shift.
Kādreizējo fabrikas strādnieku sociālekonomisko pārmaiņu pieredzes postsociālisma Lietuvā
2017
Šī maģistra darba mērķis ir sniegt vēsturiski situētu etnogrāfisku ieskatu, kas apraksta un kontekstualizē bijušo rūpnīcu strādnieku ikdienas dzīves postsociālistiskā Lietuvā. Šis pētījums seko personīgiem naratīviem par darbu kā pieredzēm socialistiskā pārvaldes sistēmā. Tas skaidro kā šīs pieredzes tiek atsauktas atmiņā un iekļautas tagadnes naratīvos. Šis etnogrāfiskais pētījums balstās vairākās datu ieguves metodēs, tai skaitā, arhīva materiālu analīzē, daļēji strukturētās intervijās, novērojumos, kā arī vizuālās antropoloģijas metodēs. Šis pētījums ir ievietojams plašākā postsociālisma antropoloģijas debatē. Tas parāda, kā kolektīvās atmiņas un kolektīvās aizmiršanas koncepti, kā arī n…
The relationship between cortisol and cognitive function in healthy older people: The moderating role of Apolipoprotein E polymorphism.
2018
The Apolipoprotein E4 (ApoE-epsilon 4) allele has been suggested as the main risk factor for late onset Alzheimer's disease (AD), whereas the ApoE-epsilon 2 allele has been proposed as a protective factor. These proposals have increased the interest in the effect of the ApoE genotype in healthy people. Additionally, high cortisol levels have been related to negative effects on cognition. However, few studies have investigated the relationship between cognitive performance and cortisol, taking into account the different ApoE alleles. For this reason, the aim of this study was to evaluate different cognitive domains (declarative and working memory, attention, and executive function) and their…
Sant’Eligio degli Argentieri: dialoghi sul destino di un rudere
2021
In meetings between the silversmiths Pietro Accardi and Silvano Barraja with Luciana Macaluso, professor of architectural design, the events that reduced the church of San Eligio in Palermo to ruins were retraced and a different destiny for the monument has been envisioned. The church was built by the silversmith confraternity in 1650 and dedicated to their patron saint, a silversmith of French origins. The earthquake of 15 January 1940 damaged the structure and, three years later, a bomb destroyed the roof of the main body. During the 1950s, the shops in the square of the same name multiplied to the point of occupying part of the church. The subsequent decline in craft activities and the g…
Conservare e raccontare / Preserving and telling,
2017
A partire dal progetto per il restauro e la valorizzazione dell'ex-chiesa di San Biagio a Cammarata (Agrigento), il saggio approfondisce una metodologia che intende il progetto come luogo di elaborazione per la riscoperta del senso dell’abitare. A fondamento del processo si collocano la lettura e l’interpretazione dello spazio esistente, per poi procedere verso l’attribuzione di senso (che a volte i luoghi hanno perduto o non hanno mai posseduto) e ad affermare la qualità responsabile del valore estetico ed etico dello spazio. Nello specifico, si riafferma il valore di un metodo che tende a svelare le qualità che il luogo o il manufatto già possiedono; che opera con misurati e semplici gest…
Modeling the insect mushroom bodies: application to a delayed match-to-sample task.
2013
Despite their small brains, insects show advanced capabilities in learning and task solving. Flies, honeybees and ants are becoming a reference point in neuroscience and a main source of inspiration for autonomous robot design issues and control algorithms. In particular, honeybees demonstrate to be able to autonomously abstract complex associations and apply them in tasks involving different sensory modalities within the insect brain. Mushroom Bodies (MBs) are worthy of primary attention for understanding memory and learning functions in insects. In fact, even if their main role regards olfactory conditioning, they are involved in many behavioral achievements and learning capabilities, as …
